Weather in Hua Hin in April

Shoulder season. April is shoulder season in Hua Hin — cheaper, quieter, and a genuine gamble. Highs average 32.9 °C, lows 27.1 °C, and rain falls on 14 days — nothing in the month is working against you.

April ranks 7 of 12 in Hua Hin: past the worst of the year but short of December, which is the month to book if the dates are open.

This is persistent light rain rather than storms: 14 wet days but only 1 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Pack for 32.9 °C days and 27.1 °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: 5 days clear 35 °C, so a serious heatwave is normal rather than notable; the day barely swings — 5.8 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 37.4 °C and the coldest night fell to 23.6 °C, and the wettest single day dropped 57 mm — roughly 83% of the month's rain in one day.

April is moderately variable: 24 mm in the driest year against 229 mm in the wettest, around an average of 69 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 9.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 73%.

How April sits in the year

Temperatures hold steady either side: 31.8 °C in March, 32.9 here, 32.1 in May. Nothing about the timing within the month matters much. Rain is the thing that moves: May brings 13 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in April

Hua Hin sits close enough to the equator that daylight barely moves all year — 12.4 hours in April, against a range of just 1.5 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 30 °C in April — 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.

April in Hua Hin versus nearby

If Hua Hin is one option among several, the nearby comparison is worth making. Bangkok is the weaker option in April — 3.7 °C warmer, 2 days less rain. Lat Krabang is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: April is a compromise. December is 35 points better and is what Hua Hin is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
