Weather in Hoi An in June

Shoulder season. June sits in between. You will get good days and you will lose some. Highs average 33.1 °C, lows 26.8 °C, and rain falls on 11 days — nothing in the month is working against you.

June ranks 7 of 12 in Hoi An: past the worst of the year but short of February, which is the month to book if the dates are open.

Rain on 11 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 33.1 °C days and 26.8 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 29 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest June day reached 37.5 °C and the coldest night fell to 24.2 °C, and the wettest single day dropped 82 mm — roughly 115% of the month's rain in one day.

June is moderately variable: 9 mm in the driest year against 213 mm in the wettest, around an average of 71 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind is light at 5.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 79%, high enough to notice on the warm days without dominating them.

How June sits in the year

Temperatures hold steady either side: 32.6 °C in May, 33.1 here, 33 in July. Nothing about the timing within the month matters much.

Daylight in June

Hoi An sits close enough to the equator that daylight barely moves all year — 13.1 hours in June, against a range of just 1.9 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 29.9 °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

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

June in Hoi An versus nearby

If Hoi An is one option among several, the nearby comparison is worth making. Qui Nhon is close enough to be a coin toss — 2.1 °C cooler, 3 days more rain. Ubon Ratchathani is close enough to be a coin toss — 2.2 °C cooler, 11 days more rain.

So: June is a compromise. February is 32 points better and is what Hoi An is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
