Has anyone been telling you, “Oh you can’t visit Phuket then; it’s off-season”.
Truth be told, there’s no “off-season” in Phuket. The island doesn’t shut its doors, and everyone hunker down for six months. Life on the island of Phuket goes on regardless of the weather – very broadly split wet season and dry season as you’re in the tropics.
There are, of course, more pleasant seasons to visit if your heart is set on long sunny days at the beach and less chance of travel plans being interrupted.
Let’s take a look at exactly what to expect in terms of climate and how the wet season may impact – but certainly not stop – your travel plans.

You will also want to balance the average temperature in Phuket with the average humidity. Being a tropical monsoon climate, the humidity can significantly change the “feels like” temperature to be many degrees warmer and explains why you feel so hot and sweaty.
The average monthly humidity in Phuket ranges from around 70% to 90%. Here is a breakdown of the average monthly humidity levels in Phuket:
- January: 73%
- February: 70%
- March: 70%

It’s important to note that humidity levels can vary depending on weather conditions and other factors, and these are just averages. Additionally, the high humidity in Phuket can make the weather feel hotter and more uncomfortable than the temperature suggests, especially during the hot season from March to May.
Staying hydrated and taking precautions against heat and humidity-related illnesses is always a good idea.
With not only the driest but the least humid months falling from January to March, these are the best months for those averse to the heat to visit.
