Hoi An weather at a glance

Hoi An sits on Vietnam's central coast, in Quang Nam province. Daytime highs stay warm in every month, and humidity rarely drops. What changes is rainfall, sea conditions and how cool the evenings feel. Typical patterns run like this: summer highs near 35°C (95°F), winter nights near 18°C (64°F), and heavier rain from roughly autumn into early winter. Month boundaries shift from year to year, so treat the table as a pattern, not a promise. Vietnam's national weather agency publishes the official forecasts and warnings.

Check today's forecast

A guide cannot tell you if it is raining this afternoon. Use the forecast from Vietnam's meteorological agency, or any live app, for that. Read rain chance and rain amount separately. A high chance of light showers is a different day from a low chance of a downpour. Pay attention to humidity and the feels-like temperature, because they decide comfort more than the headline number. For official warnings, see the national hydrometeorological service.

Hoi An weather by season

Dry and hot months suit beach time and cycling through the rice fields. Midday heat is the trade-off, so start before 8 a.m. Cooler months bring softer light and easier walking, with some drizzle. The wetter months bring grey skies, lower crowds and a real chance of disruption. Our guide to the full timing decision weighs these trade-offs month by month. As an illustration only, a mid-range double room might cost about 900,000₫ a night in a quiet wet-season week versus 1,500,000₫ in peak summer. Treat that as a budgeting example, not a quoted rate, and compare current listings.

Rain, typhoons and flooding in Hoi An

Typhoon season on the central coast generally falls in the autumn months, and Vietnam's agency issues the official storm warnings. Heavy rain can raise the Thu Bon River, and the Old Town riverside is the low-lying part most exposed to flooding. An Bang Beach and Cua Dai Beach can have rough sea days when storms pass offshore, so swimming may be unsafe. Flights and road transfers via Da Nang can be delayed during storms. Read rainy-season planning before booking autumn dates. If water rises, follow local advice and move valuables off ground floors. Our flood guidance covers what to do next.

Winter and December weather

Winter is cooler than many visitors expect, with nights near 18°C (64°F) to 20°C (68°F) at the cool end. December can still bring showers early in the month, then dry out. Bring a light jacket for evenings by the river. See our notes on December conditions for what to expect.

Planning around the weather

Hot afternoons call for a siesta or an indoor stop. Rain suits tailor fittings, cooking classes and cafes. Dry days suit the beach and cycling. Go out early for the heat, and save the lantern-lit Old Town streets for the evening, when temperatures ease.

• Rain: book a tailor fitting, a cooking class or a long cafe stop.
• Heat: ride or walk before 8 a.m., then rest indoors from midday.
• Dry day: head to An Bang Beach or cycle the countryside.
• Mistake to avoid: scheduling a beach day or riverside dinner on a storm-warning day.

What to pack for Hoi An

Bring a light rain jacket or poncho, breathable cotton or linen clothing, and sun protection. Sandals with grip handle wet Old Town streets better than smooth soles. A waterproof phone pouch or dry bag cover protects electronics in sudden downpours.

Air quality and UV

UV and air quality change daily and by hour. Check a live air-quality and UV reading before long outdoor days, and apply sunscreen even under cloud. The national tourism authority lists general travel advisories.
