Weather in Ho Chi Minh City in July

A hard month. July is a hard month in Ho Chi Minh City, and worth planning around. You should expect rain on 24 days of the month, which is more days wet than dry.

July ranks 5 of 12 in Ho Chi Minh City: past the worst of the year but short of December, which is the month to book if the dates are open.

Rain on 24 of the month's 31 days, 6 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 87% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 19 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest July day reached 35.2 °C and the coldest night fell to 22.6 °C, and the wettest single day dropped 108 mm — roughly 52% of the month's rain in one day.

July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 379 mm against 95 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 207 mm average is a reasonable planning figure, not a promise.

Wind is light at 8.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 87% is the real story though — it is the number that decides how the day feels, not the 30.4 °C.

How July sits in the year

Temperatures hold steady either side: 31.3 °C in June, 30.4 here, 30.3 in August. Nothing about the timing within the month matters much.

Daylight in July

Ho Chi Minh City sits close enough to the equator that daylight barely moves all year — 12.7 hours in July, against a range of just 1.3 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 28.7 °C in July — warm enough that the water offers no relief from the heat. The sea peaks at 29.9 °C in May and bottoms out at 25.3 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

July in Ho Chi Minh City versus nearby

If Ho Chi Minh City is one option among several, the nearby comparison is worth making. Vũng Tàu is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Cần Thơ is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: July is a compromise. December is 29 points better and is what Ho Chi Minh City is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
