Weather in Ubon Ratchathani in March

A hard month. March is a hard month in Ubon Ratchathani, and worth planning around. Daytime highs average 36.8 °C and the afternoon is not negotiable — outdoor plans move to early morning or evening.

March ranks 9 of 12 in Ubon Ratchathani: past the worst of the year but short of December, which is the month to book if the dates are open.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for heat management rather than style: shade, water, and a schedule that gives up on the middle of the day.

What the averages hide

Averages flatten a month, and this one hides a few things: 24 days of the month clear 35 °C — that is not a heatwave, it is the month. Across the twenty years measured, the hottest March day reached 42 °C and the coldest night fell to 14.1 °C, and the wettest single day dropped 29 mm — roughly 91% of the month's rain in one day.

This is the volatile part. March rainfall has ranged from 1 mm to 97 mm across the twenty years measured — a 96 mm spread around an average of 32 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 7.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 50%.

How March sits in the year

Temperatures hold steady either side: 35.6 °C in February, 36.8 here, 36.6 in April. Nothing about the timing within the month matters much. Rain is the thing that moves: April brings 5 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in March

Ubon Ratchathani sits close enough to the equator that daylight barely moves all year — 12 hours in March, against a range of just 1.8 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

An inland climate

Despite being inland, the year stays fairly even: 17.8 °C between the year's warmest afternoons and coldest nights.

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.

March in Ubon Ratchathani versus nearby

If Ubon Ratchathani is one option among several, the nearby comparison is worth making. Siem Reap is close enough to be a coin toss — within a degree on temperature, 3 days more rain. Nakhon Ratchasima is close enough to be a coin toss — within a degree on temperature, 2 days more rain.

So: March is a compromise. December is 33 points better and is what Ubon Ratchathani is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
