Weather in Surat Thani in February

A good month. February works. It is not the peak, but nothing about it fights you. The heat itself is manageable at 30.4 °C, but 83% humidity is what you will actually feel.

February is the highest-scoring month of the twelve. The nearest rival is January, and the month at the other end of the year is May.

Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. Natural fibres and a second shirt for the day. At 83% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 18 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest February day reached 34.4 °C and the coldest night fell to 19.8 °C, and the wettest single day dropped 42 mm — roughly 135% of the month's rain in one day.

This is the volatile part. February rainfall has ranged from 1 mm to 120 mm across the twenty years measured — a 119 mm spread around an average of 31 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 5.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.

How February sits in the year

Temperatures hold steady either side: 29.2 °C in January, 30.4 here, 31.9 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

Surat Thani sits close enough to the equator that daylight barely moves all year — 11.8 hours in February, against a range of just 1.1 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: 9.9 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, January is the trade worth considering — 11 points weaker on weather, and materially quieter.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

February in Surat Thani versus nearby

If Surat Thani is one option among several, the nearby comparison is worth making. Krabi is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Hat Yai is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: February is the answer for Surat Thani. If it is booked out or priced out, January is the next best thing at 11 points behind, and May is the month to keep off the shortlist.
