Ho Chi Minh City Weather in September

September weather

September is hot, sticky and often grey. The high is 30°C, and rain falls on 24 days, so you may get caught in a sharp downpour. It's wetter than August, but October is wetter still. With little sunshine, long outdoor plans can feel tiring.

You can still enjoy short walks between showers. Try the covered sections of Ben Thanh Market, or spend a rainy spell at the War Remnants Museum. Save a full day outdoors for a clearer forecast; muddy paths and sudden rain can spoil a walk in Tao Dan Park.

Festivals and holidays

Vietnam's National Day falls on September 2. Expect public events, possible road closures and changes to opening hours, especially around central sights. Check local notices before heading out that day.

The Mid-Autumn Festival can also fall in September, though its date changes each year. In Cholon, the city's historic Chinatown, lantern shops and seasonal treats bring a festive feel. Mooncakes are a classic gift and snack.

Crowds and practical tips

September is part of the wet season, so it's generally quieter than the drier months of December and January. You may find better hotel deals than in peak season, though prices vary. National Day and Mid-Autumn celebrations can make particular spots busier.

If you hate crowds, visit Ben Thanh Market on an ordinary weekday rather than during a holiday. Travelling with kids? Keep a flexible plan for rainy afternoons.

For a useful local stop, duck into the covered aisles of Binh Tay Market in Cholon when showers start. You can browse its food stalls and see local trade without needing to cross town in the rain. Don't count on clear skies for a long riverside walk.
