Ho Chi Minh City has a tropical climate with two distinct seasons: a dry season and a wet season. Unlike many tropical destinations, the wet season in Saigon doesn’t mean constant rain — it means afternoon downpours of 30–90 minutes, after which the sky usually clears. Understanding the seasonal rhythm helps you pack appropriately and set the right expectations.

The dry season (November–April)

November to February is the most comfortable period: temperatures in the low-to-mid 20s Celsius (77–82°F), low humidity, almost no rain, and clear skies. December and January are peak tourist months with slightly higher accommodation prices and busier attractions. For most international visitors, this window — particularly December to early February — is the ideal time to visit.

March to April is the pre-monsoon transition: temperatures climb toward 35–38°C (95–100°F) and humidity builds. It’s still the dry season so there’s little rain, but the physical experience of walking around in this heat mid-day is exhausting. Structure your days around early mornings and evenings, rest indoors during 11am–3pm, and drink significantly more water than you think you need.

The wet season (May–October)

The pattern is: mornings are warm and often sunny; clouds build through the afternoon; rain arrives between 2pm and 6pm, usually intense for 30–60 minutes; the evening clears and can be very pleasant. With sensible scheduling — mornings for outdoor sightseeing, late afternoon for indoor activities — the rainy season is very manageable.

The advantages of visiting during the wet season: accommodation is cheaper by 15–30%, crowds at major attractions are smaller, and the city is greener and cooler than during the hot dry season. Many regular visitors prefer the wet season precisely because of the reduced tourist pressure.

Holidays and events to be aware of

Tết Nguyên Đán (Vietnamese Lunar New Year, January or February) is the most significant holiday in Vietnam. During the 3–7 days around Tết, many local restaurants, markets, and shops close — the city empties as Saigonese travel home. Worth experiencing if you know what you’re getting into; worth avoiding if you want a normal visit with full food and activity access.
