OCT–MAR (Peak Season)
Weather & Temperature
Countrywide cool-dry season with comfortable days and lower rainfall. Averages 23–31°C in most regions; humidity ~60–75%. Andaman Sea (Phuket, Krabi, Similan) is calm and clear Nov–Mar; Gulf of Thailand (Samui–Phangan–Tao) can see heavier showers Oct–Dec due to the northeast monsoon. Northern highlands can drop to 12–18°C at night.
What to Expect
Blue skies, best beach and diving conditions on the Andaman side, lively atmosphere, and the year’s highest prices and crowds in late Dec–Jan. October is a shoulder month with improving weather; March warms up and can feel summery. Northern air quality may dip late Feb–Mar due to seasonal agricultural burning.
