Weather in Phuket and tourist seasons

November to March is nicest

November to March is nicest

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 cool breezes and clear, sunny, dry days. The southwest monsoon runs from May through October and tends to be wetter.

Unlike parts of Thailand further to the north, Phuket sees fairly consistent temperatures year-round, with lows in the mid-20s (Celsius) and peak temperatures in the mid-30s. March and April are the hottest months, while November through January is the coolest and driest time of year.

This is, not surprisingly, also the most popular time for visitors, since it coincides with the miseries of winter in the Northern Hemisphere, with the result that Phuket fills up.

Although the weather in Phuket is reliably sunny most of the year, there is more chance of rain from April to October. This can mean cooler, cloudy days, or hot sunny weather with tropical storms in the late afternoon and evening. The weather can get uncomfortably humid, too. Sea breezes cool the temperatures even in hot season but expect sea and swimming pools to be warm year-round. See a month by month weather breakdown.

Green season in Phuket

From April to November the wind swings to the southwest, bringing wetter days and higher humidity. 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. October usually brings a final burst of rain storms before the skies clear for the next ‘high’ season.

Heavy swells make swimming dangerous, and there are frequent drownings despite red flags and signs warning people not to swim. On the upside, surfers love the ‘low season’ as there are decent swells to ride at many of the west coast beaches.

But despite attempts by the tourism industry to rebrand this as ‘Summer Season’, the impression that it pours with rain for six months on end seems hard to dislodge from tourists’ minds. Many residents, however, prefer this time of year because the cloudy weather can make it cooler as the season progresses, and the rain makes the island greener.

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 dark, wet and gloomy. 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.

Dry season in Phuket

From December through February, rainfall levels drop to about 40mm a month on average. March remains dry, but it begins to feel hotter and more humid.

Be sure to protect yourself from the strong sun!

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. If there is any rain, it rarely lasts more than an hour.

Weather in Phuket in February
The weather in February in Phuket is still very pleasant, with very little chance of rain, cool evenings and very little humidity, though it can still be quite hot in the middle of the day. Being the dead of winter in Europe, North America and North Asia, this is a popular time for tourists from those regions to visit, so the island remains busy.

Weather in Phuket in April
April is the hottest month weather-wise in Phuket and, indeed, Thailand, and the rains are eagerly awaited as day-time temperatures head for 40 Celsius.

August is often one of the wetter months as the monsoon weather reaches its peak, and you are most likely to have lots of cloudy days and downpours.
