Quick Summary: Ho Chi Minh City weather splits into a dry season (December–April) and a wet season (May–November). The best time to visit is December to February, when daytime temperatures sit around 26.6–27.4°C, rain days drop to their lowest, and humidity is at its most comfortable. April is the hottest month, averaging 29.2°C.
Ho Chi Minh City’s climate is shaped less by four distinct seasons and more by the tug-of-war between two monsoons sweeping over the flat delta terrain the city sits on. Canals and the Saigon River keep the air heavy with moisture even on the driest days, so the weather here always carries a tropical hum.

Weather by Seasons
Dry Season (December–April): Average temperatures range 26.6–29.2°C, with April running hottest. Rain days stay low, from 3 in February up to 11 in April as the season turns over into the rains. Skies are mostly clear, and this is when locals and visitors alike head outdoors.
Wet Season (May–November): Average temperatures stay a touch cooler at 26.7–28.8°C, but rain days jump to 18–29 per month, peaking July through September at 29 days. Rain usually falls in short, intense afternoon bursts rather than lasting all day. According to long-term climate records from Climate-Zone.com, relative humidity in Ho Chi Minh City climbs from around 59% in March to nearly 90% in September — the clearest sign the wet season has arrived.
Daily Weather & Humidity Insights
Humidity swings hard across the year — roughly 60–70% during the driest months (February–March) to the mid-to-high 80s at the height of the rains (June–September). Daytime highs typically run well above the monthly averages, with the widest day-night gap in the dry season (up to roughly 9–10°C between a hot afternoon and a cooler night) narrowing to about 6–7°C once cloud cover moves in for the wet season. Afternoons can feel sticky even when it isn’t raining, especially from May onward.
What to Wear and Pack
- Lightweight, breathable cotton or linen clothing for the heat and humidity.
- A compact umbrella or rain poncho from May through October — showers arrive fast and often.
- Comfortable, breathable walking shoes for exploring on foot.
- Sunscreen, sunglasses and a hat for the strong midday sun, especially in the dry season.
- A light layer for heavily air-conditioned malls, offices and restaurants.
Essential Local Tips
- Midday sun (11am–3pm) is intense year-round; plan walking tours for early morning or late afternoon instead.
- Flash flooding in low-lying districts is common during heavy wet-season downpours (July–October) — check local news before heading out if rain is forecast.
- Aim for the dry season for the clearest skyline and riverfront photos; wet-season storms roll in fast but usually clear quickly, leaving dramatic skies. See more things to do in our our full Ho Chi Minh City travel guide.
