Must like the rest of South East Asia, Phuket has a tropical climate with a rainy or monsoon season. The hottest time of year in Phuket is between April and May where we see temperatures reaching between 27C to 36C (80F to 95F). During this time you also get short bursts of heavy showers, which is a great as this helps to cool things down a bit.
The best time to visit Phuket is between November and March, as it is less humid and slightly cooler. You’ll find temperatures ranging from 24C to 32C (75F to 89F)
The monsoon season is between May and November, but Phuket is still very hot during this time and it doesn’t necessarily rain every day, it is still a very pleasant time to visit and you are guaranteed to see the sun shining in between showers.
