Weather in Vũng Tàu in June

A hard month. June asks something of you. Go in knowing what. You should expect rain on 25 days of the month, which is more days wet than dry.

June ranks 11 of 12 — near the bottom of Vũng Tàu's year. January is the month that works, and the swing between the two is 39 points, which is a different holiday rather than a slightly better one.

Rain on 25 of the month's 30 days, 8 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 84% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 20 days top 30 °C, making the heat continuous rather than occasional; the day barely swings — 5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 37.4 °C and the coldest night fell to 23.4 °C, and the wettest single day dropped 146 mm — roughly 65% of the month's rain in one day.

June is moderately variable: 107 mm in the driest year against 637 mm in the wettest, around an average of 224 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind is light at 10.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 84%, high enough to notice on the warm days without dominating them.

How June sits in the year

Temperatures hold steady either side: 32.7 °C in May, 30.7 here, 29.8 in July. Nothing about the timing within the month matters much.

Daylight in June

Vũng Tàu sits close enough to the equator that daylight barely moves all year — 12.7 hours in June, against a range of just 1.2 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 29.5 °C in June — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

June in Vũng Tàu versus nearby

If Vũng Tàu is one option among several, the nearby comparison is worth making. Ho Chi Minh City is close enough to be a coin toss — within a degree on temperature, 3 days less rain. Cần Thơ is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: June is a compromise. January is 33 points better and is what Vũng Tàu is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
