Weather in Siem Reap in February

A hard month. February asks something of you. Go in knowing what. Daytime highs average 35.9 °C and the afternoon is not negotiable — outdoor plans move to early morning or evening.

February ranks 4 of 12 in Siem Reap: 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 3 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: 21 days of the month clear 35 °C — that is not a heatwave, it is the month. Across the twenty years measured, the hottest February day reached 40.6 °C and the coldest night fell to 14.1 °C.

This is the volatile part. February rainfall has ranged from 1 mm to 46 mm across the twenty years measured — a 45 mm spread around an average of 16 mm. The average is real but almost no individual February looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 5.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 53%.

How February sits in the year

Temperatures hold steady either side: 33.9 °C in January, 35.9 here, 36.7 in March. Nothing about the timing within the month matters much. Rain is the thing that moves: March brings 6 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in February

Siem Reap sits close enough to the equator that daylight barely moves all year — 11.7 hours in February, against a range of just 1.6 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: 16.1 °C between the year's warmest afternoons and coldest nights.

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.

February in Siem Reap versus nearby

If Siem Reap is one option among several, the nearby comparison is worth making. Ubon Ratchathani is close enough to be a coin toss — within a degree on temperature, 2 days less rain. Nakhon Ratchasima is a better bet in February — within a degree on temperature, the same number of rain days.

So: February is a compromise. December is 24 points better and is what Siem Reap is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
