Rany season in Phuket is often referred as Green season and begins in May until October. The question you may as yourself: How is Scuba Diving in terms of the weather during rainy season in Phuket?

The weather in Phuket is warm all year round. Temperatures range between 25 – 34 degree Celsius. Humidity will range between 60% – 95% throughout the year adding to the feeling of warmth.

The seasons are broken into two distinct seasons “Wet Season” (summer) and “Dry Season” (winter).

In the high season, the average rainfall is 18 days in November and 11 days in December. From January to March it’s around 5 days per month, making this the driest and most popular time to travel.

In the off-season, the wettest months are toward the end of the rainy season, September and October, with an average of 22 and 25 rain days and around 300mm rainfall per square metre.

During the rest of the rainy season, just over half the days are actual rainy days.

The probability of a few rainy days during a holiday is relatively high, but at the same time there will also be a lot of dry and sunny days. Even in the rainy season, for example, Phuket still offers 6 to 7 hours of sun per day.


Weather is always a top question, but is one that is very difficult to comment on. Whatever I say, Mother Nature seems to do the opposite :) We do our best to advice you.
