Weather in Hua Hin in March

Shoulder season. March is shoulder season in Hua Hin — cheaper, quieter, and a genuine gamble. Highs average 31.8 °C, lows 25.7 °C, and rain falls on 10 days — nothing in the month is working against you.

March ranks 5 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.

Rain on 10 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 31.8 °C days and 25.7 °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: 27 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest March day reached 36.3 °C and the coldest night fell to 20.1 °C, and the wettest single day dropped 65 mm — roughly 107% of the month's rain in one day.

This is the volatile part. March rainfall has ranged from 7 mm to 286 mm across the twenty years measured — a 279 mm spread around an average of 61 mm. The average is real but almost no individual March looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 9.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 74%.

How March sits in the year

Temperatures hold steady either side: 30.5 °C in February, 31.8 here, 32.9 in April. Nothing about the timing within the month matters much. Rain has already shifted: 6 days more than February had.

Daylight in March

Hua Hin sits close enough to the equator that daylight barely moves all year — 12 hours in March, 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 28.9 °C in March — warm enough that the water offers no relief from the heat. The sea peaks at 30.5 °C in May and bottoms out at 27.8 °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

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.

March 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 March — 5 °C warmer, 2 days less rain. Lat Krabang is close enough to be a coin toss — 2.1 °C warmer, 1 day less rain.

So: March is a compromise. December is 24 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.
