Weather in Hat Yai in November

Shoulder season. November is shoulder season in Hat Yai — cheaper, quieter, and a genuine gamble. You should expect rain on 28 days of the month, which is more days wet than dry.

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

Rain on 28 of the month's 30 days, 11 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: the day barely swings — 3.4 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest November day reached 31.2 °C and the coldest night fell to 23.5 °C, and the wettest single day dropped 164 mm — roughly 47% of the month's rain in one day.

November is moderately variable: 175 mm in the driest year against 744 mm in the wettest, around an average of 346 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.

Wind is light at 9 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 28.7 °C.

How November sits in the year

Temperatures hold steady either side: 29.3 °C in October, 28.7 here, 28.2 in December. Nothing about the timing within the month matters much. Rain is the thing that moves: December brings 6 days less of it, so pushing the dates later buys drier weather.

Daylight in November

Hat Yai sits close enough to the equator that daylight barely moves all year — 11.8 hours in November, against a range of just 0.8 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 29 °C in November — warm enough that the water offers no relief from the heat. The sea peaks at 30.6 °C in May and bottoms out at 27.9 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

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 Hat Yai versus nearby

If Hat Yai is one option among several, the nearby comparison is worth making. Kota Kuala Muda is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Krabi is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: November is a compromise. February is 27 points better and is what Hat Yai is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
