Da Nang Surf Forecast Guide — How to Predict Waves

This summer, Da Nang served three-meter tubes—and we knew a week ahead they’d be clean, not fat. The recipe was classic: NE→E lines with 10–12 s, light W-offshore at first light, and mid/rising tide over tuned sandbars. If you only skim the “1.0 m” in an app, you’ll miss it.

This guide teaches you to read like a local—the field guide to How to Predict Waves at My Khe: spot the right angle that actually reaches the beach, treat period as the engine, use gusts (not averages) to make wind calls, and let tide fine-tune—not decide—the session. Do that, and you’ll start calling real surf 3–5 days out (sometimes two weeks on typhoon pulses).

Cams on, Windguru up, Tides checked. Let’s read it right and score the next window.

How to read a Da Nang forecast (from scratch)

Starting from scratch: a My Khe session really comes down to four things in the forecast—swell angle, period, wind, and tide. Everything else is secondary.

Swell angle
Waves are energy traveling in lines from distant storms; the angle is their compass bearing. My Khe faces east, so it lights up when those lines arrive from the NE–E window (ENE/E). In any app, peek at the primary-swell direction (e.g., “NE 60°”). The farther it swings toward SE, the less punch reaches the beach.

Period
Period is the seconds between wave crests—the rhythm that carries power. Longer period = more push and longer, cleaner walls on the sandbars. In forecasts it’s the “s” after height, like 0.8 m @ 9 s. In Da Nang, think <7 s mushy, 8–10 s sweet spot, >10 s rare but excellent. Size only makes sense next to period: 0.8 m @ 9 s often beats 1.0 m @ 6 s.

Wind
Local wind either grooms or ruins the face. Offshore (from land to sea) holds the lip up; onshore (from sea to land) ruffles it. Here, a light W-sector offshore (W/WSW/WNW) up to ~8–10 kn is your friend. An E onshore at 12–15 kn+ turns things messy fast—especially after mid-morning.

Tide
Tide is just water level. Too low and waves trip early and dump; too high and they get fat and slow. Da Nang isn’t super tide-sensitive, but a mid or gently rising tide is the easiest starting point, especially on borderline days.

One-line test: NE–E swell + ≥8 s period + light W offshore + mid/rising tide = go. Miss one → maybe (bring a longboard). Miss two → skip and wait for the next window.

Quick feels

• GO: NE 70°, 0.8 m @ 9 s, W 6 kn, rising tide → clean, fun on fish/mid-length.
• Maybe: E 95°, 0.5 m @ 7 s, glassy → inside peelers for a longboard.
• Skip: E 100°, 1.0 m @ 6 s, E 14 kn, low tide → closeouts and foam; grab coffee.

Swell Direction & Window (NE/E)

Picture Da Nang’s shoreline as an open door facing sunrise. Swell doesn’t just “arrive”—it travels in at an angle, and that angle decides whether the wave walks through the door with any power. When lines march in from the north-east through east (roughly 50–100°), they hit My Khe almost head-on. Energy doesn’t bleed away down the beach; it stands up on the sandbars and draws longer, cleaner faces. That’s the working window here: NE/E is the angle most likely to turn open-ocean energy into surf you can actually ride.

Shift toward ESE/SE (~100–115°) and the picture changes. The swell brushes the beach from the side, more of the push turns into longshore current, peaks shorten, closeouts multiply. In summer you often add short period (5–7 s) windswell—plenty of texture, not much drive. Exceptions exist and they’re memorable: a long-period typhoon pulse with glassy mornings or a light offshore can make that south-eastern angle come alive. Just don’t bank on it as your baseline.

The Sơn Trà headland isn’t a magic swell maker; it’s a wind shield. On breezy NE days it can tidy up the southern stretches of My Khe, but very N/NNE swells lose punch wrapping the point, so south of it they arrive weaker. Hence the classic play remains simple: favor NE→E.

Quick tells (one glance):

• Green light: primary swell 50–100° (NE→E)
• Yellow: 100–115° (E→ESE) only if period is long (≥9–10 s) and wind is kind
• Red: well <40° or >120°—low odds for My Khe today

Period (Wave Period)

Think of period as the rhythm of the ocean—the seconds between wave crests. It’s not just a timing number; it’s what gives a wave its shape and push. Longer period swells reach deeper into the water, feel the bottom sooner, stand up taller on the sandbars, and draw those smooth, connected walls you actually want to surf. Short-period windswell, by contrast, breaks quick and crumbly, then shuts down.

Why this matters at My Khe: the beach is open and sandy, so the difference between 6 s and 9 s is night and day. 0.8 m @ 9 s can run with line and hold a face; 1.0 m @ 6 s often turns into choppy closeouts. That’s why locals say “period makes the wave.”

A neat side effect of longer period is sets: energy travels in packets, so you get longer lulls and then a punchier series. That’s the group showing up. If you like a back-of-the-napkin rule for timing distant swells: group speed scales with period, so you can think ~1.5 × period = knots (very rough, but handy). Ten seconds? Call it ~15 kn of swell travel—useful when you’re eyeballing when a pulse might arrive after a storm spins up.

Quick tells

• < 7 s — short, mushy, breaks fast.
• 8–10 s — sweet spot for Da Nang: cleaner takeoffs, more face to work with.
• > 10 s — rare summer/typhoon treats: fewer waves, bigger push, real lines.

Height vs Face on the Spot

Apps rarely show what you actually see when a wave stands up in front of you. Most forecasts list significant wave height out in deep water (an average of the tallest third), or a generic “surf height.” Once that swell hits the sandbars at My Khe, it transforms: long-period lines slow down, steepen, and refract toward shore, so the face you drop into can be taller than the number in the app—or smaller, if the period is short and the wind is wrong.

That’s why 1.0 m in a forecast ≠ 1.0 m on the face. A 1.0 m @ 6 s windswell often turns into knee-to-waist, fast closeouts. A 0.8 m @ 9 s pulse can stand up to waist-chest with room to draw a turn. Give it 1.2 m @ 10 s on a mid/rising tide and a light W offshore, and you’ll see chest-shoulder sets with clean entry. Same “height,” different period, wind, and tide → totally different surf.

Now, about sets. Swell energy travels in packets, not a conveyor belt. You’ll get a lull, then a cluster of bigger waves—the set. Set waves carry more push and cleaner shape; in between are smaller fillers. For beginners, two simple habits change everything: count the minutes between sets (helps timing), and paddle out during the lull, not when the horizon goes dark. Expect the occasional “rogue” set that’s a head taller than the average—don’t wait on the inside for it.

Pocket rules: think height + period first, then let wind (offshore vs onshore) and tide fine-tune your expectation of the actual face you’ll surf.

Wind: Direction & Thresholds

Wind is the last brushstroke on the canvas. It can groom a wave so it stands tall and smooth, or ruffle it into white, fast closeouts. Because My Khe faces east, anything with a west in it (W / WSW / WNW) is offshore—air flows from land to sea and holds the lip up. Anything with an east in it (E / ENE / ESE) is onshore—air pushes from sea to land and roughens the face. Northerlies or southerlies act as crosswinds; cross-offshore (WNW/WSW) is usually okay, cross-onshore (ENE/ESE) crumbles quicker.

Morning is your friend. Most days the breeze is light at dawn, then a sea-breeze from the E builds late morning into the afternoon. If you’re choosing between early and perfect or later and windy, pick early. The Sơn Trà headland can also knock a little bite off strong NE breezes for the southern stretches of My Khe—worth checking when it’s blustery.

Use these ranges as a simple feel-guide (knots ≈ 0.5 × m/s):

• 0–6 kn: glassy to light groom—great for all boards.
• 7–10 kn: still fine; fish/mid/long feel best; shortboards OK if period has punch.
• 11–15 kn: maybe—look for cross-offshore corners or shelter; beginners stick to longboards.
• >15 kn onshore: skip for beginners—expect chop, drift, and short, closing sections.

Two small tricks make wind calls more accurate:

• Gusts vs average: if the app shows 8 kn average but 15 kn gusts, it rides like the higher number—downgrade your expectations a notch.
• Arrows: most surf apps plot the direction the wind comes from. A W arrow pointing toward the ocean = offshore; an E arrow pointing inland = onshore.

Put it all together with your swell read: a light W-offshore (≤8–10 kn) can turn modest lines into clean runners; E onshore ≥12–15 kn can ruin even a promising forecast, especially after mid-morning.

Tide & Sandbars

Tide is just water level. Sandbars are the little underwater dunes that make a wave stand up. At My Khe the tidal range is modest, so the tide nudges quality rather than totally flipping the day. Most of the time you’re not hunting a magic minute—you’re looking for the level that lets the bars do their job.

Why mid / rising works so often: with a bit of water on the banks, the swell can shoal, steepen, and peel without tripping too early. As the tide comes in, closeouts ease, sections link up, and you get more “run” on the face. On borderline days (small height or short period), that extra lift from a rising tide is the difference between knee-high crumble and an actual line you can ride.

Extremes are where things fall apart. Dead-low can expose the inner bar and turn sets into dumpy shorebreak that shuts down fast—great for body whomps, not for clean rides. Top-of-the-high can drown the banks: waves feel fat, slow, and fade before they stand. After storms, banks get reshaped; peaks move. That’s normal—think of the beach as “breathing.” The day after the blow (or the morning after the evening pulse) can be sneaky-good once the water finds the new contours.

A few practical reads:

• Small / marginal day: aim for rising toward mid—give the swell more bar to work with.
• Solid day: mid tide is the safe bet; mid-falling can still be fun if the wind is clean, but watch rips.
• Not clicking where you are: walk 300–500 m—there’s usually a better-shaped bank up or down the beach.

Bottom line: let tide fine-tune the call you already made on angle, period, and wind. If those three are green, mid or gently rising will help the banks turn numbers into waves.

My Khe Surf Forecast: How to Read & Calibrate

You don’t need ten tabs—just three, each with a job. Surfline tells you the story (primary/secondary swell, cams, a human-friendly “is it worth it?”). Surf-Forecast gives clean numbers by the hour (height, period, direction). Windguru nails the breeze (speed, gusts, when it swings onshore). Read them in that order, then apply My Khe’s local rules.

Start with Surfline. Note the primary swell angle and period; ignore the color rating until you’ve checked the raw pieces. Hit the cam for 10–20 seconds—do you see sets with shape, or a fast shorebreak? If the card says “E/NE swell 8–10 s,” you’re in the right lane for Da Nang.

Cross-check on Surf-Forecast. This is your ruler: confirm the period and direction hour by hour. For My Khe, NE→E is the working window; 8–10 s is the sweet spot. A humble 0.7–1.0 m @ 9 s often surfs better than a bigger 6-second windswell. If they list a secondary swell, make sure it isn’t a short, messy bump that will clutter the face.

Then open Windguru. Look at wind by the hour and gusts (gusts ride like the higher number). My Khe faces east, so W-sector is offshore, E is onshore. Most days give you a dawn glass-off and an E sea-breeze by late morning. If Windguru shows W 4–8 kn until ~9:30 and E 12–15 kn after 10:30, the plan is obvious: dawn patrol or nothing.

Now add the local calibration:

• Angle: My Khe likes NE/E. ESE/SE can work only with longer period and clean wind. Very N or S angles underdeliver on the city beach.
• Period: “Period makes the wave.” Aim for ≥8 s; >10 s is gold (often typhoon-related).
• Wind: W-offshore ≤8–10 kn grooms; E onshore ≥12–15 kn trashes shape for beginners.
• Time of day: First light → ~9:30 is the A-window. A second chance can appear near sunset if the sea-breeze eases.
• Tide: Not super sensitive here, but mid/rising helps borderline days.
• Sơn Trà effect: In NE breezes, the southern stretches of My Khe can be a touch cleaner; the northern side may feel a hair bigger but breezier. Walk the beach 300–500 m to find a better bank.

When the sites disagree, use this hierarchy: trust Windguru for wind timing, Surf-Forecast for period/direction, and treat Surfline’s rating/copy as a summary, not the verdict. You need two greens out of three (angle/period on point + friendly wind) to commit. One green is a longboard maybe. Zero greens? Save it.

Two quick sanity checks before you grab the board:

• Face vs. forecast: a “1.0 m” line at 6 s can be knee-waist closeouts; 0.8 m @ 9 s can be waist-chest runners.
• Gusts win: if Windguru says 8 kn with 15-kn gusts, expect it to surf like 12–15 kn.

Do this loop a few mornings in a row—Surfline glance → Surf-Forecast numbers → Windguru timing → beach reality—and you’ll have My Khe “dialed” faster than any app can promise.

Seasons & Best Time to Surf in Da Nang

Da Nang runs on a simple rhythm. November to March the NE monsoon feeds the city steady, shorter-period swell. Most days you’ll find something to ride, especially if you’re in the water at first light before the onshore builds. April to August is mostly small and glassy—great for longboards and soft-tops—unless a distant storm wakes the coast. The bridge months, September to November, are the wild cards: early NE pulses start to appear, and the odd long-period typhoon line can turn My Khe on for a morning or two.

Here’s the quick feel of each slice of the year:

Season	What it feels like	Best daily window	Boards that shine
Sep–Nov (transition)	Mix of early NE pulses; occasional longer lines from passing typhoons	Sunrise to mid-morning; some cleaner sunsets	Fish / mid-length; shortboard when a typhoon pulse hits
Nov–Mar (NE monsoon)	Regular, rideable surf; punchy but shorter period	Dawn patrol—out before the sea-breeze	Mid-length / fish; longboard on small days; shortboard on punchy ones
Apr–Aug (low-surf)	Mostly knee-waist and glassy; fun insiders	First light; small evening windows if the breeze eases	Longboard / SUP; soft-top for learners

Typhoon notes (read once, remember forever)

When a storm spins well offshore to the E or ESE—think roughly 500–1200 km out—and points lines NE→E with 10–14 s period, Da Nang can light up even in summer. Your shot is dawn on “day 0” before the sea-breeze, or “day +1” after the wind relaxes and the sandbars settle. Aim for a mid or gently rising tide. If the beach forecast shows a stiff E onshore (≈12–15 kn or more) during your slot, shelve it and wait—wind kills shape faster than any number can save it. And treat it like weather, not just waves: rips get stronger, peaks wander, and river junk sometimes drifts through the lineup.

5-Step Method: How to Predict Waves in Da Nang

Here’s the quick loop locals run before they even sip coffee. Do it in this order and don’t overthink.

1) Angle + engine check (the gate).
Open your forecast and look at the primary swell. If it’s NE→E with period ≥ 8 s and height ≥ 0.6 m, you’ve cleared the first gate. That combo means the swell actually reaches My Khe and has enough push. E/ESE can still work, but only if the period is long (≈ 9–10 s) and the wind is kind.

2) Wind clock (your make-or-break).
Scan 06:00–10:00. You want a light W-sector offshore ≤ 8–10 kn; that keeps faces tidy. Treat gusts as the real feel—8 kn average with 15 kn gusts rides like 12–15. If it flips to E onshore ≥ 12–15 kn before you paddle out, the shape goes fast.

3) Tide frame (fine-tune).
Aim to start on mid or gently rising tide. It gives the sandbars just enough water to stand the wave up. On borderline days (small height or short period) this is the difference between peelers and knee-high crumble. Avoid dead-low + onshore: classic dumpers.

4) Cross-check (two sources, two minutes).

• Surfline: confirms angle/period and gives you the cam—do you actually see sets with shape?
• Windguru: nails wind by the hour and gusts (believe the gusts).
• Surf-Forecast (optional): sanity-check the period/height timeline.
  If two of these agree on your window (angle/period look right and wind stays light offshore), your confidence just went up.

5) Make the call.

• GO: three greens (angle+period, wind, tide) → suit up.
• MAYBE: two greens → bring a longboard or pick the cleanest bank.
• SKIP: fewer than two → watch cams, save it for the next window.

Quick examples

• GO: NE 70°, 0.8 m @ 9 s, W 6 kn till 9:30, mid-rising → fish/mid-length, clean lines.
• MAYBE: E 95°, 0.5 m @ 7 s, glassy at dawn → longboard on the inside.
• SKIP: E 100°, 1.0 m @ 6 s, E 14 kn by 08:30, dead-low → closeouts.

Decision Table — Go / Maybe / Skip

Quick legend: Dir = swell/wind direction; Hs = height (m); Tp = period (s).
Offshore at My Khe = W-sector (W/WSW/WNW). Onshore = E-sector (E/ENE/ESE).

#	Swell (Dir, Hs @ Tp)	Wind (Dir, kn)	Tide	Board	Call	Why it plays out this way
1	NE 70°, 0.8 @ 9	W 6	Mid-rising	Fish / Mid	GO	Clean angle, sweet-spot period, light offshore = runners.
2	E 95°, 0.7 @ 10	Glass 2	Rising	Fish / Mid	GO	Long Tp rescues the more easterly angle; glass helps it stand.

4	E 100°, 1.0 @ 9	W 8 → E 12 (11:00)	Rising	Fish → wrap early	GO (early)	Morning window before the sea-breeze.
5	NE 70°, 0.6 @ 8	W 5	Mid	Longboard / Mid	GO	Borderline size but period + offshore make it fun.
6	NE 65°, 1.5 @ 10	W 10	Any	Shortboard	GO	Solid pulse; period/angle forgive tide.
7	ESE 115°, 1.0 @ 10	W 4	Mid-rising	Fish / Mid	MAYBE	Works only with long Tp + clean wind; look for best bank.
8	NE 55°, 0.5 @ 7	W 6	Rising	Longboard	MAYBE	Small + shortish Tp; rideable on logs.
9	E 100°, 0.6 @ 8	ENE 10	Mid	Longboard	MAYBE	Cross-onshore adds texture; logs still glide.
10	NE 80°, 0.9 @ 8	E 12	High	Mid / Fish	MAYBE	Enough push to survive some onshore at high tide.
11	E 95°, 0.8 @ 9	W 7 (gust 15)	Rising	Fish / Mid	MAYBE	Gusts ride like 12–15 kn—watch for bump as morning wears on.
12	NE 70°, 0.4 @ 9	W 3	Mid	Longboard / SUP	MAYBE	Clean but tiny; great for learners.
13	NE 60°, 1.0 @ 6	W 6	Mid	Longboard	MAYBE	Short Tp = dumpier; logs can still steal insiders.
14	E 100°, 0.8 @ 7	E 8	Low	Longboard	MAYBE	Low tide + short Tp = quick peaks; pick mellow corners.
15	NE 65°, 0.9 @ 8	E 14	Rising	Mid	MAYBE/Skip	Onshore near 15 kn chews faces—only try if banks look good.
16	NE 70°, 1.6 @ 12	W 4	Mid	Shortboard	GO (sets)	Typhoon-style lines: fewer waves, big push—be patient for sets.
17	E 105°, 1.3 @ 11	WSW 6	Mid	Shortboard / Fish	GO	Long Tp offsets oblique angle; cross-off still fine.
18	NNE 30°, 1.0 @ 9	W 5	Mid	Fish	MAYBE	Wrap needed south of Sơn Trà; expect smaller, peaky surf.
19	SE 130°, 0.9 @ 10	W 6	Rising	Mid / Fish	MAYBE	Marginal angle; period + offshore might tease a bank into life.
20	E 100°, 1.2 @ 8	E 18	Any	—	SKIP	Strong onshore closes it out; drift and chop win.
21	NE 70°, 0.7 @ 7	E 15	Low	—	SKIP	Short Tp + onshore + dead-low = dumpers.
22	ESE 115°, 0.6 @ 6	E 10	Any	—	SKIP	Small windswell from the side—no real lines.
23	NE 65°, 2.0 @ 9	W 12 (gust 18)	Mid-falling	Shortboard (experienced)	MAYBE (advanced)	Power + gusty cross-off; rips strong—know your limits.
24	E 95°, 0.9 @ 9	Glass 0–2	High	Fish / Mid	GO	Glassy high can smooth sections when period’s there.
25	NE 75°, 0.8 @ 8	W 8 → E 12 (10:30)	Rising	Fish	GO (early) / SKIP (late)	Classic dawn window before sea-breeze flips.

How to use the table: match what your apps show (angle, Hs@Tp, wind, tide). If your row looks like a GO, paddle out. If it’s a MAYBE, bring a longboard or hunt a better bank (walk 300–500 m). If it’s a SKIP, save your energy and check the next window (sunrise or pre-sunset).

Post-Storm & Special Windows

Storms are messy, but they’re also the days that make memories. In Da Nang the pattern is simple: there’s a “day 0” window when the wind finally eases while the swell still has teeth, and a “day +1” cleanup after the ocean catches its breath. Read those two right and you’ll score.

Day 0 — the gap.
As the system moves away, My Khe can flip from blown-out to groomed in a single morning. You’re looking for that first light W-sector offshore at dawn with long-period lines still marching in. Expect sets, lulls, then more sets—don’t fight every pulse. Sit a touch wider than usual, watch two cycles, and time your paddle on the lull. Pick a mid or gently rising tide so the bars hold shape. If the wind snaps back to E onshore, session’s over.

Day +1 — the cleanup.
Energy drops a notch, but the period often stays long. Sandbars settle, sections connect, and rips organize into clear channels. This is the day for shoulder-high runners and longer rides. The lineup spreads out; walk 300–500 m to find the best reformed bank rather than parking in front of the towers.

Sandbars after a blow.
Big pulses knock down the inner bar and carve bowls beside rip channels. From the beach, look for darker slits (the rips) with peeling shoulders just down-drift—those bowls are where you’ll find shape. If a peak that fired yesterday goes dead, don’t wait—peaks migrate; your new bank is likely a few hundred meters along the same contour.

Rips, debris, and water quality.
Rips are stronger and straighter after storms. Use them to paddle out, not to sit in: angle out, then slide sideways to the shoulder. Keep your eyes open—storms flush bamboo, branches, plastic and river silt. If the water’s chocolate-brown and you see big debris moving in the lineup, that’s a red flag—skip or downsize the risk.

Timing quirks.
Two frequent gifts: a glass-off right at first light on day 0, and a second, shorter glass-off near sunset on day +1 if the gradient relaxes. Tide still matters less than the wind, but on marginal size the push toward mid-tide is the difference between dumpy and drawn-out.

Gear & headspace.
Fresh leash, fins tightened, a touch more paddle fitness than you think you need. Long lulls mean discipline: count sets, breathe, don’t burn your arms chasing the first dark line on the horizon.

A quick storm plan (stick it in your notes):

• Check for dawn W-offshore with the swell still long-period → go early (day 0).
• If the wind’s settled and the ocean looks organized → favor day +1.
• Start on mid / rising tide, scout for rip-bowls, walk for a better bank.
• Use rips to exit, not to wait. If debris is heavy or onshore returns, call it.

When in doubt, don’t paddle out. There’s nearly always another morning in Da Nang.

Safety & Etiquette (Short & Useful)

Rip currents.
At My Khe they show up as darker “rivers” with fewer breaking waves. Use them to paddle out, not to sit. If one grabs you: don’t fight straight in—go sideways to the shoulder, then in on the whitewater. After storms and during the NE monsoon, rips are stronger and cleaner—treat them with respect.

Lifeguards & flags.
Stay outside swimmer zones and obey whatever the beach crew sets that day—ropes, cones, whistles, flags. If it’s flagged no swimming, it’s a no for surfing too. When patrols ask you to move, just move—there’s a long beach and plenty of sandbars.

Fishing gear & boats.
Early and late you’ll see fixed nets and small boats working near shore. Give nets a wide berth (look for float lines) and never try to “duck” under them. Keep distance from boats; your leash and their prop are a bad combo.

Lightning & storms.
Tropical squalls roll in fast. If you see lightning or hear thunder within ~30 seconds of a flash, clear the water—boards are lightning attractors, and storms here can flip wind from glass to chaos in minutes.

Lineup basics (don’t be that person).

• Right of way goes to the surfer closest to the peak and already riding. No drop-ins.
• Don’t snake (paddle around someone at the last second to steal position).
• Paddle wide around the peak; don’t cut through the takeoff zone.
• Hold on to your board—don’t throw it on a closeout; protect the people behind you.
• New to the spot? Sit a little wide, watch three sets, then blend in.

Quick pocket rules: leash on, fins tight, give space, share sets, help swimmers if lifeguards ask. The ocean will always be here tomorrow—make choices you’re happy to repeat.

Tools You’ll Use (and how)

You don’t need a dashboard. Four tabs are plenty.

Surfline (My Khe). Open the spot. First glance: primary swell angle and period. Then the only thing that truly matters—watch the cam for 10–20 seconds. If you see lined-up sets (not just foamy shorebreak), you’ve got something. Treat the 16-day view as mood music; plan off the next few days.

Windguru / Windy. This is the wind clock. Check the hour you’ll surf, not the whole week. W / WSW / WNW is offshore here (polishes the face). E is onshore (adds chop). Gusts ride like the higher number, so 8 kn with 15-kn gusts feels closer to 12–15.

Surf-Forecast (My Khe). Your ruler. Table view tells you height, period, direction by the hour. For My Khe the combo to care about is NE→E with 8–10 s. A neat truth: 0.8 m at 9 s often beats 1.0 m at 6 s.

Tides4Fishing. Just grab today’s high/low and see if you can hit a mid or gently rising tide. That’s the easiest water level for the sandbars to work.

Your one-minute routine: Surfline (NE→E and ≥8 s, cam looks good) → Windguru (light W-offshore through your slot) → Surf-Forecast (around 0.6–1.2 m @ 8–10 s) → Tides4Fishing (aim for mid/rising). Two of those line up? Go. One? Maybe with a longboard. None? Save it for the next window.

When the apps disagree (they will), believe what you can see on the cam, then believe the wind timing, then use period + angle to judge if the energy even reaches My Khe. Tide is the fine-tune, not the headline. Set the same units everywhere (m, s, kn) and keep everything in local time—the numbers will start reading like a picture.

FAQ

Which wind direction is best for surfing in Da Nang?
Light offshore from the W-sector (W/WSW/WNW) is best because it holds the face up and cleans the lip. Aim for ≤8–10 kn in the morning. E onshore adds chop fast; once it reaches ≈12–15 kn, quality drops sharply, especially for beginners.

What is a good swell period for Da Nang?
8–10 seconds is the sweet spot: enough deep-water energy to stand up on My Khe’s sandbars and draw longer, cleaner walls. >10 s is excellent but rarer (often typhoon-related). <7 s behaves like windswell—short, mushy peaks that close out quickly.

What size waves are good for beginners at My Khe?
Look for 0.6–1.0 m with 8–10 s period, light W offshore, and mid/rising tide. That combo gives gentle takeoffs, slower sections, and longer rides. Bigger surf or strong E onshore accelerates the wave and adds chop—better left to confident surfers.

Da Nang is ideal for first waves. Learn more in our Beginner Surfing in Vietnam guide.

Is it better to surf in the morning or afternoon?
Morning wins. Winds are usually lighter or offshore at dawn, so faces stay smooth; by late morning an E sea-breeze often turns it choppy. If you miss dawn, check just before sunset—occasionally the breeze eases and shape returns for a short window.

Which tide works best in Da Nang?
My Khe isn’t super tide-sensitive, but mid or gently rising tide is the safest starting point. It gives sandbars enough water to let waves peel without dumping early. Dead-low often creates shore-dump closeouts; top-of-high can feel fat and slow.

How windy is too windy to surf?
For most surfers, E onshore ≥12–15 kn turns waves messy and short. Treat gusts as the real feel—8 kn average with 15-kn gusts rides like 12–15. Cross-offshore (WNW/WSW) can be okay; strong cross-onshore (ENE/ESE) breaks sections apart.

Are 1-ft waves surfable?
Yes—for longboards/soft-tops when it’s glassy. A small line like 0.3–0.4 m @ 8–10 s on mid/rising tide can be fun for learners close to shore. Shortboards generally need more push; onshore wind or very short period will kill what little shape there is.

How to tell how big the waves will be?
Don’t read height alone. Combine height + period + wind + tide to estimate the face on the beach. Rule of thumb: 0.8 m @ 9 s often surfs bigger (waist-chest) than 1.0 m @ 6 s windswell. Check the cam for sets—energy arrives in packets, so expect lulls.

Where is the best beach to surf in Da Nang?
My Khe (city beach) is the most consistent and accessible. It likes NE→E swell and W-offshore mornings. In strong NE breezes, the southern stretches can feel a touch cleaner thanks to Sơn Trà’s shelter; walk 300–500 m to hunt the best sandbar.

Can you swim in the ocean at Da Nang?
Generally yes, but follow lifeguard flags and stay clear of rip currents and fishing nets/boats. After storms, expect stronger rips and occasional debris; water can turn silty near river mouths. If there’s lightning or thunder nearby, get out immediately.

Conclusion

That’s the whole trick: read the angle, period, wind, tide—then trust what you see on the cam. In Da Nang, dawn is your best friend: NE–E lines, 8–10 s, a light W offshore, and a mid/rising tide will do more for your session than any hype number ever could. Run the 5 steps, glance at the table, pick a bank, go surf.
