🏊 Swimmable sea this month (≥22°C)

Koh Lanta sits in the tropics in Thailand, and the 2015–2024 weather record gives its sunshine a clear shape: the January peak reaches a 91/100 sun score, with daytime highs around 30°C — a solid base for a beach trip.

The year runs from average lows of 25°C in September to highs of 32°C in March. Rain is most likely in October, when about 87% of days see meaningful rainfall, and least likely in February (23%). If 24°C is your bar for proper warmth, count on January–December.

Averaged by season, sun scores land at 82 for spring, 77 for summer, 72 for autumn and 89 for winter — with typical afternoons of 31°, 29°, 29° and 31°C respectively. In short: plan around winter if you can, keep spring as the fallback, and go into autumn with managed expectations (its season score is 72). If your dates are flexible, January buys you 30°C warmth at the quiet end of the season.
