Weather in Phuket
Phuket has a balmy tropical climate, with two distinct seasons that shift with the direction of the monsoons. The northeast monsoon season, from November through March, brings cooler breezes and sunny, dry days. The wet southwest monsoon runs from May through October.
Unlike other parts of Thailand, Phuket sees fairly consistent temperatures year-round, with lows in the mid-20s (Celsius) and peak temperatures into the mid-30s. March and April are the hottest months, while November through January is the coolest time of year as far as weather in Phuket is concerned.
Dry season
When November begins, the rains end, and this is the time of year when those from cold climates begin fleeing to Phuket to enjoy the sun-drenched beaches. Weather in Phuket is at its best and humidity levels drop, making it more comfortable for sipping cocktails in the shade of beach umbrellas. There may be an occasional shower, but these rarely last more than an hour.
From December through February, precipitation levels drop to about 40mm/month on average. March remains dry, but it begins to feel hotter and more humid.
Green season
From April to November the weather in Phuket can be wet. April is the steamiest month, with daytime temperatures creeping towards the 40-degree level and heavy thunder clouds bringing humidity levels up. Rain showers are frequent but brief.
Rainfall is heavier from May through August, but the storms are often quick to pass and there are still many sunny days during these months. It's a nice time of year to visit, as the beaches are less crowded and hotel rates lower. Surfers love the ‘low season’ as there are some decent swells to ride at many of the west coast beaches.
Rain gear and umbrellas are a must during September and October, as these months see an average rainfall of more than 300mm. During this time the weather in Phuket can be miserable. While there's often still a fair amount of sunshine, don't be surprised to find it bucketing down for days on end. It's a good time to hit the shopping centres and spas.
