The Best Months for Hoi An — and What the Rainy Season Really Means
Hoi An is only 30 km from Da Nang, so the weather is nearly the same. One thing differs: the old town sits on the Hoai River, which makes flood season matter far more here than in Da Nang.
Month by month
| Month | Weather | Worth knowing |
|---|---|---|
| Jan–Feb | Mild, cool at night, little rain | Lunar New Year: very busy, and many places shut for a few days |
| Mar–Apr | Dry, gentle sun, most comfortable | The best window of the year |
| May–Jun | Bright, warming up | Good for the beach; avoid walking at midday |
| Jul–Aug | Hottest, hard sun | Peak domestic season, high room rates |
| Sep | Rain begins | Quiet, good prices, rain still light |
| Oct–Nov | Heavy rain, flood season | The Hoai can rise and flood the riverside streets for one to three days |
| Dec | Rain easing, cool | Lanterns photograph beautifully in the cool air |
What the rainy season actually does
Three specific effects, not vague ones:
- Boats to Cham Island stop in rough seas — common from October to January. Do not book island accommodation to a fixed date.
- Riverside streets can flood by tens of centimetres for one to three days in October and November. Locals move by sampan, and many visitors find it memorable — but the old houses and assembly halls close.
- The coconut forest and river tours pause when the water is high.
The full moon — the date worth planning around
On the 14th of each lunar month the old town switches off its electric lights. Only lanterns and candles, bai choi folk singing, and paper lamps on the Hoai. It is Hoi An at its best and its busiest — book the room and the car early, especially when the full moon lands on a weekend.
Hoi An at Tet
The old town is decorated and packed. Two things to know first:
- Many restaurants and shops close for two to four days around the first day of the new year
- Rooms and cars both cost more; book three or four weeks ahead

The short answer
- Want a safe bet → February to April
- Want to swim → May to August
- Want it quiet and cheap → September, accepting bursts of rain
- Avoid → October and November if your schedule is fixed and cannot move
FAQ
When is the best time to visit Hoi An?
February to April is the best window: dry, mild, gentle sun, not yet hot. May to August is hot and bright but good for the beach. September to December is the rainy season, and October to November brings the floods.
Can you visit Hoi An in the rainy season?
Yes, but stay flexible. Central Vietnam's rain usually comes in bursts of a few hours rather than all day, and the old town is beautiful wet. The real issue is October and November: the Hoai River can rise and flood the riverside streets for one to three days, and boats to Cham Island stop.
What is special about the full-moon night?
On the 14th of each lunar month the old town switches off its electric lights and uses only lanterns and candles, with bai choi folk singing and paper lamps on the river. It is the loveliest night of the month and also the busiest — book your room and your car early.
