How hot is it in Thailand during September?
Expect heat in Thailand during September. The temperature hits about 32℃ during the day, falling away to a balmy 25℃ at night. Of course, the high humidity will make it feel even hotter. The UV index will be high at this time of year, so protection against skin and eye damage is needed. Try to limit exposure between 10am and 4pm. Apply broad spectrum SPF 30+ sunscreen every few hours, even if it's cloudy, or more frequently after sweating or swimming, and wear UV-blocking sunglasses too, and bear in mind that bright surfaces, such as sand and water increase UV exposure.
Does it rain in Thailand during September?
On average, there will be 13 rainy days during the month, amounting to 248.9mm in total. That's a lot of rain. For comparison, the wettest months in the UK typically sees between 80mm and 100mm, depending on where you are. Due to the high temperature and humidity, you might expect lots of thunderstorms, however they're actually fairly infrequent at this time of year. On average, September will see just 6 days that produce a storm.
Is it windy in Thailand during September?
You're unlikely to experience any strong winds. Expect a light breeze that picks up slightly at times in September. The high humidity and warm temperature will make the breeze feel warm, so any cooling effect will be limted.
How warm is the sea in Thailand during September?
The water around Thailand reaches a very pleasant 30℃ during September. This is very warm, and will feel bath-like. People who normally feel the cold will find this temperature perfectly acceptable. The hot air temperature and relatively high humidity will mean that you will feel comfortably warm when coming out of the water.
