People think Hoi An is a dry tropical town with a rainy month or two. It's wetter than that. September to December each see 24 to 29 rain days, and the summer before it runs 33°C (91°F) to 35°C (95°F), so you're packing for heat, mosquitoes and real downpours, often in the same week.

Season by season
Cool season
December–FebruaryHighs are 24°C (75°F) to 25°C (77°F) and lows 19°C (66°F) to 21°C (70°F), which feels mild. But December is still very wet with 28 rain days, easing to 15 by February. Pack light layers, a rain shell and a long-sleeve top for evenings.
Shoulder season
March–AprilThis is the sweet spot. March is 27°C (81°F) with 11 rain days, and April jumps to 32°C (90°F) with just 4. It's the best time for cycling to An Bang beach and walking the lantern-lit old town at night. Bring light clothes, sunscreen and repellent.
Hot season
May–AugustHighs of 33°C (91°F) to 35°C (95°F) with lows of 26°C (79°F) to 27°C (81°F), so nights don't cool off. Rain days pick up too, 13 in May and 17 a month from June to August. Pack loose, quick-drying clothes and a way to stay cool.
Rainy season
September–NovemberThe heaviest rain of the year, with 25 rain days in September, 29 in October and 24 in November. The old town can flood when the Thu Bon River rises. Pack a rain shell, quick-dry clothes and shoes you don't mind getting soaked.
