Can I swim at Hoi An beaches year-round?
No, swimming is not safe year-round. Best: March–August (calm water, warm, clear). Avoid: October–November (typhoon season, rough waves 2–3m). January–February is cool (22–24°C), windy, some days swimmable. An Bang Beach is safest — lifeguards at beach clubs, calmer than Cua Dai.
The seasonal reality
Hoi An has a beach climate — but not all months are swimmable. The monsoon and typhoon seasons create dangerous conditions.
Quick answer:
- Best: March–August (calm, warm, clear)
- Okay: September, December (hit or miss)
- Avoid: October–November (typhoons), January–February (cool, rough)
Month-by-month breakdown
January–February: Cool and windy
Water temp: 22–24°C Conditions: Northeast monsoon, waves 1–2m Swimmable: Some days, but cold for most
Winter in central Vietnam. The water is cool (locals say it’s cold). Waves are rough — not great for swimming.
Who swims: Locals (used to cooler water), hardy travelers. Verdict: Wait for March if beach time is a priority.
March–May: Best conditions
Water temp: 25–28°C Conditions: Calm, clear, light breeze Swimmable: Yes, excellent
This is why people come to Hoi An. The water is warm, visibility is good, waves are gentle.
Crowds: Moderate (not yet summer peak) Verdict: Ideal beach time.
June–August: Hot and crowded
Water temp: 28–30°C Conditions: Warm, calm, occasional afternoon showers Swimmable: Yes, very good
Summer heat. The water feels like bathwater. Afternoon thunderstorms roll in — usually brief, but can be intense.
Crowds: Peak season (Vietnamese summer holidays) Verdict: Great for swimming, go early to avoid crowds.
September: Transition
Water temp: 27–29°C Conditions: Variable — calm some days, rough others Swimmable: Usually yes, check conditions
The monsoon is shifting. Most days are fine, but weather can change fast. Keep an eye on forecasts.
Crowds: Thinning out Verdict: Okay, but have a backup plan.
October–November: Typhoon season
Water temp: 25–27°C Conditions: Rough waves (2–3m), strong currents, heavy rain Swimmable: NO
This is dangerous. Typhoons roll through the region. Waves reach 2–3 meters. Currents are deadly. Beaches close. Flights get cancelled.
What happens:
- Speedboats to Cham Islands are cancelled
- Beach clubs close during storms
- Hotels advise guests not to swim
- Local news warns of drowning risks
Verdict: Do not swim. Visit cultural sites instead — Japanese Bridge, temples, museums.
December: Improving
Water temp: 23–25°C Conditions: Cooling down, waves decreasing Swimmable: Some days
The typhoon season ends. Water is cooling. Some days are calm and swimmable, others are still rough.
Verdict: Hit or miss — check conditions daily.
Safety tips
Rip currents are the biggest danger. They look like calm channels between breaking waves — but they pull you out to sea.
How to escape:
- Don’t panic — you can’t outrun the current
- Don’t swim directly toward shore — you’ll exhaust yourself
- Swim parallel to the beach — escape the current’s pull
- Once free, swim back to shore at an angle
- Wave one arm if you need help
Beach clubs save lives. At An Bang, clubs like Soul Kitchen and La Plage have staff who watch swimmers and can throw rescue rings. Swim near beach clubs, not in isolated sections.
Check flags:
- 🟢 Green: Safe to swim
- 🟡 Yellow: Caution — moderate hazards
- 🔴 Red: Dangerous — do not enter water
Not all beaches have flags. An Bang has some signage. Cua Dai public beach has none.

My recommendation
Plan beach time for March–August. This is when Hoi An shines — warm water, calm seas, good conditions.
If visiting October–November: Skip the beach. Explore Hoi An’s cultural sites — temples, museums, cooking classes. Day trip to My Son ruins. Wait for better conditions.
Always check conditions: Ask your hotel, look at the beach before entering, watch for warning signs. If in doubt, don’t swim.
Swim at An Bang, not Cua Dai. An Bang has beach clubs with oversight. Cua Dai public beach has no lifeguards and dangerous currents.
