How is the Weather in Phuket in March?
In March, the weather in Phuket gets hotter, and the sea and sky remain spotlessly blue. Expect prices to stay high and roads and beaches to be busy. Some rain may appear in short, welcome showers, mostly at night. Everything in Phuket is open and buzzing, and the islands around see a ballet of speedboats and longtail boats. March is the last month of the high season before the heat and humidity of April.

Insider Tips
March is the hottest month of the high season. The midday heat can be intense. Plan your day around it. Beach time is best in the early morning or late afternoon when the sun is lower. Hotel prices remain high but start to ease toward the end of March as the transition to low season approaches. Late March offers better value than early March. This is your last chance to visit the Similan Islands before they close in mid-May.
Book a trip while conditions are still perfect and the islands are still accessible. The sea is warm, almost too warm for some. At 29°C, it doesn’t provide much relief from the heat. A pool with shade becomes more attractive than the beach during the hottest hours. Occasional brief showers are a welcome relief from the heat. They usually pass quickly and cool things down.
Don’t let a rain forecast worry you. The best way to check real conditions is my daily weather timelapses. Each video shows a full day compressed into one minute. Nothing helps more than seeing what a typical March day actually looked like last year.
March Weather Through the Years
March marks the transition from high season to hot season. The crowds start thinning, but the heat builds. It’s a month of contrasts. The sea remains perfect. Calm, clear, blue. The beach conditions are as good as in January or February. The difference is in the air temperature. March is noticeably hotter than the previous months.
Locals know March as the beginning of the hot season. The comfortable temperatures of December through February give way to proper tropical heat. Midday feels intense. The humidity starts climbing. For visitors from cold climates, the heat can be overwhelming. Those who struggle with humidity may prefer the earlier high season months. But for many, March offers the best of both worlds: perfect beach conditions with fewer crowds and slightly lower prices than peak season.
The occasional afternoon shower that appears late in March is actually welcome. It breaks the heat and cools things down. These brief rains are a preview of the monsoon months to come, but they don’t disrupt activities.
