How warm is it in Phuket during September?
September is typically the coolest month in Phuket, although we use the term cool in a relative sense! Expect heat, with the temperature hitting about 29℃ during the day, falling away to a balmy 27℃ 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 Phuket during September?
On average, there will be 14 rainy days during the month, amounting to 374.4mm 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. There's a good chance that you'll catch a thunderstorm during your trip.
Is it windy in Phuket during September?
You're unlikely to experience any strong winds. Expect a gentle breeze that increases to moderate at times during 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 Phuket during September?
The water around Phuket reaches a very pleasant 29℃ 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.
