Kata Beach in the dry season

  • November to February: the most reliable months for the beach, with the calmest sea and the most sun. It is also high season, with the highest prices, especially at Christmas and New Year.
  • March and April: still dry, but hotter and more humid; the sea is generally still good for the islands.
  • May to October: the monsoon. September is usually the wettest month (about 315 mm), followed by October (about 313 mm) according to a chart consulted in October 2026. Showers are often brief but heavy.

During the monsoon: sea and safety

Sunset in the rain over the Andaman Sea

On the west coast, notably at Patong, red flags often mark dangerous swimming, and some boat trips are cancelled or moved. Island excursions depend on the sea: see the Phi Phi islands and Phang Nga Bay. The Similan Islands are generally closed during the monsoon; check the season's reopening dates.
