Thailand’s weather varies by region and month. The cool season (November to February) brings temperatures of 25–30°C in Bangkok and the north, with low humidity.

For a detailed breakdown, see our 10 day weather forecast UK for comparison, though Thailand’s tropical pattern is different.
Is it safe to travel to Thailand during the rainy season?
Yes, but you need to plan. The rainy season, particularly September and October, can cause flooding in Bangkok and northern provinces. Check the UK weather hub for general travel advice, but for Thailand, monitor local warnings. The south’s east coast (Koh Samui) has a later rainy season, peaking in November. Always carry a rain jacket and allow extra travel time.
