We've looked at the most up-to-date weather data for Thailand, covering the last 12 years up to 2026, plus we've asked our team of travel bloggers for their first-hand experiences in order to answer the most frequently asked questions about Thailand weather in March.

How hot is it in Thailand during March?

Expect heat in Thailand during March. The temperature hits about 38℃ during the day, falling away to a balmy 26℃ at night. The UV index will be very high at this time of year, so you'll need to protect your eyes and skin. Avoid sun exposure between 10am and 4pm where possible. If outdoors, find shade, wear sun-protective clothing, wear UV-blocking sunglasses and generously apply broad spectrum SPF 30+ sunscreen every hour or so. Don't be fooled by cloudy skies! Remember that bright surfaces, such as water and sand will increase UV exposure.

Does it rain in Thailand during March?

On average, there will be 2 rainy days during the month, amounting to 43.7mm in total. That's broadly comparable with the amount of rain we see in England during the summer months, and would be considered dry. There's a small chance that you'll catch a thunderstorm during your trip.

Is it windy in Thailand during March?

You're unlikely to experience any strong winds. Expect a light breeze that picks up slightly at times in March. With moderate humidity, any breeze will have a very welcome cooling effect.

How warm is the sea in Thailand during March?

The water around Thailand reaches a very pleasant 29℃ during March. This is very warm, and will feel bath-like. People who normally feel the cold will find this temperature perfectly acceptable. The hot air temperature will mean that you will feel comfortably warm when coming out of the water.
