Weather in Surat Thani in November

A hard month. November is a hard month in Surat Thani, and worth planning around. You should expect rain on 24 days of the month, which is more days wet than dry.

November ranks 5 of 12 in Surat Thani: past the worst of the year but short of February, which is the month to book if the dates are open.

Rain on 24 of the month's 30 days, 10 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 87% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 9 days top 30 °C — hot spells arrive, but they break; the day barely swings — 4.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest November day reached 33.3 °C and the coldest night fell to 20.3 °C, and the wettest single day dropped 126 mm — roughly 39% of the month's rain in one day.

November is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest November on record still delivered 631 mm against 137 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 320 mm average is a reasonable planning figure, not a promise.

Wind is light at 5.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 87% is the real story though — it is the number that decides how the day feels, not the 29.3 °C.

How November sits in the year

Temperatures hold steady either side: 29.7 °C in October, 29.3 here, 28.9 in December. Nothing about the timing within the month matters much. Rain is the thing that moves: December brings 5 days less of it, so pushing the dates later buys drier weather.

Daylight in November

Surat Thani sits close enough to the equator that daylight barely moves all year — 11.7 hours in November, 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

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.

November 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, 2 days more rain. Hat Yai is close enough to be a coin toss — within a degree on temperature, 4 days more rain.

So: November is a compromise. February is 25 points better and is what Surat Thani is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
