Weather in Hoi An in April

A good month. April works. It is not the peak, but nothing about it fights you. The heat itself is manageable at 31.2 °C, but 84% humidity is what you will actually feel.

April ranks 4 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 7 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. 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. Across the twenty years measured, the hottest April day reached 39.3 °C and the coldest night fell to 19 °C, and the wettest single day dropped 67 mm — roughly 137% of the month's rain in one day.

This is the volatile part. April rainfall has ranged from 2 mm to 143 mm across the twenty years measured — a 141 mm spread around an average of 49 mm. The average is real but almost no individual April looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 6.5 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 April sits in the year

Temperatures hold steady either side: 28.6 °C in March, 31.2 here, 32.6 in May. Nothing about the timing within the month matters much. Rain is the thing that moves: May brings 5 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in April

Hoi An sits close enough to the equator that daylight barely moves all year — 12.5 hours in April, 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 26.8 °C in April — warm enough to stay in as long as you like. The sea peaks at 29.9 °C in June and bottoms out at 24.1 °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.

April in Hoi An versus nearby

If Hoi An is one option among several, the nearby comparison is worth making. Qui Nhon is a better bet in April — 2.5 °C cooler, 2 days less rain. Ubon Ratchathani is the weaker option in April — 5.4 °C warmer, 4 days more rain.

So: April is a compromise. February is 19 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.
