Weather in Chiang Mai in February
Thailand · 20-year averages, February
A good month. February works. It is not the peak, but nothing about it fights you. Highs average 32.7 °C, lows 17.7 °C, and rain falls on 1 days — nothing in the month is working against you.
February ranks 4 of 12 in Chiang Mai: 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 1 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 32.7 °C days and 17.7 °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: 5 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest February day reached 37.9 °C and the coldest night fell to 11.7 °C, and the wettest single day dropped 30 mm — roughly 600% of the month's rain in one day.
February is dependably dry, and that reliability is the point: across the twenty years measured, the wettest February on record still only managed 38 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Februarys brought 30 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.
Wind is light at 1.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 56%.
How February sits in the year
The month is on the way up: 3.8 °C warmer than January, and March adds another 3.1 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.
Daylight in February
February sits at the dark end of Chiang Mai's year — 11.5 hours of daylight against 13.3 at midsummer, gaining 0.5 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.
An inland climate
Despite being inland, the year stays fairly even: 20.8 °C between the year's warmest afternoons and coldest nights. Within February itself the daily swing is 14.9 °C, so mornings and afternoons need different clothes.
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.
February in Chiang Mai versus nearby
If Chiang Mai is one option among several, the nearby comparison is worth making. Luang Prabang is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Udon Thani is close enough to be a coin toss — within a degree on temperature, 2 days more rain.
So: February is a compromise. December is 21 points better and is what Chiang Mai is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
