Kata in January

November through April is peak season for good reason - the weather is dry, the seas are calm, and you can actually plan outdoor activities without checking the rain radar every hour. December and January are the busiest months, which means higher prices but also the most restaurant and tour options. February through April is the sweet spot - still great weather but fewer crowds and better deals on accommodation. The monsoon season from May to October gets a bad rap, but it's not constant rain. You'll get heavy downpours in the afternoon, then clear skies for sunset. Plus, everything is cheaper and greener during this time. Just avoid September and October when the storms can be genuinely intense and some restaurants close down completely.
