March’s weather in detail

High temperatures and little chance of rain can be expected in Bangkok and central Thailand, making sightseeing hard work, so plan for shorter experiences rather than all-day visits.  

Predominantly dry weather continues in Khao Sok National Park, although humidity levels are high and increasing temperatures can hit 33°C.

In the south, dry, sunny weather is the order of the day with plenty of blue skies and little chance of rain. Average daily temperatures of 26-31°C can be expected, with the west coast beaches of Phuket, Khao Lak & Krabi marginally warmer than Koh Samui and the east coast beaches. Favourable diving conditions continue off the west coast with a good chance of spotting manta rays and whale sharks during March.
