Hoi An is small, walkable, and at its best Feb–April. Outside that window, you risk monsoon flooding (Sept–Nov) or extreme heat (May–Aug). Here’s the breakdown.
Last verified: May 6, 2026.
Quick answer
Best: February–April. Dry, warm, manageable crowds. Worst: September–November (monsoon flooding can leave streets under 1m of water).
Month-by-month
- Feb–Apr: 22–28°C, low humidity, dry. Best window. Tet Feb 17, 2026 closes things for ~5 days.
- May–Jun: 28–35°C, hot and increasingly humid. Beach great. Old Town brutal at midday.
- Jul–Aug: 30–35°C peak heat. Tourist peak. Avoid if heat-sensitive.
- Sep–Oct: Monsoon hits. Old Town floods regularly Oct–Nov.
- Nov: Tail-end of monsoon, cooler (24–28°C), occasional flooding, cheap.
- Dec–Jan: Cooler (20–25°C), some rain, peak Christmas-NY tourist demand drives prices up.
Full Moon Lantern Festival (the big draw)
On the 14th day of every lunar month, Hoi An’s electric lights are switched off and the Old Town lights only by lanterns. 2026 dates: Feb 14, Mar 16, Apr 14, May 14, Jun 13, Jul 12, Aug 11, Sep 9, Oct 9, Nov 8, Dec 7. Best months for this experience: March, April, October (weather + atmosphere balance).
Beach season (An Bang + Cua Dai)
- Best: April–August (warm water, calm sea)
- Worst: October–December (rough sea, beach erosion at Cua Dai)
Tailoring shops timing
If you’re getting clothes tailored, leave 5+ days in Hoi An. The major shops (Yaly, Be Be, A Dong Silk) need fittings + adjustments. Don’t compress this into 2 days.

Practical tips that make the difference
- Plan in advance: book major attractions + restaurants 4-8 weeks ahead in peak season
- Use the local apps: country-specific transport, payment, and food delivery apps work better than generic international ones
- Carry small cash: card acceptance varies; €20-50 in local currency saves moments
- Travel insurance: even a $50 policy saves you from $5,000+ medical bills
- Photograph everything important: passport, BRP, important addresses, emergency numbers
Common mistakes to avoid
- Booking too tight: build 30-50% buffer between commitments. Strikes, weather, jet lag all cause delays
- Skipping local etiquette: brief research on greetings, tipping, and dress codes saves embarrassment
- Eating at tourist-trap restaurants near monuments: walk 2-5 minutes off main squares for better food + better prices
- Underestimating walking: most European + Asian cities are walked, not driven. Comfortable shoes essential
- Ignoring transit cards: city travel cards (Oyster, Suica, Navigo, etc.) are 30-50% cheaper than single tickets
When to consider professional help
For more complex situations — multi-country tax planning, complicated visa applications, or substantial property purchases — engaging a regulated professional saves money and stress in the long term. Look for: OISC-registered immigration advisers (UK), Spanish gestores (Spain), German Steuerberater (Germany), or cross-border tax specialists (any country).
