Thailand travel guide

Best time to visit Thailand from the UK

Best value: Apr, Oct. Nov–Mar: dry and cooler. Busiest and priciest: Nov–Mar, Jul.

Each bar is the average temperature in Bangkok for that month, and its colour shows the season for visitors: best value (good weather, fewer crowds and lower prices), busiest and priciest, or quiet (off-peak, sometimes because the weather is poorer).

• Our pick: April and OctoberThe warmest of the best-value months (27–31°C), with fewer crowds than peak season.
• Peak season: Nov–Mar, JulUsually 25–30°C. The busiest time, so book flights and rooms early and expect higher prices.
• Quiet season: May–Jun, Aug–SepAround 27–30°C. The cheapest and least crowded time, though often because of rain or heat.
• Warmest: April (31°C) · coolest: December (25°C)A 6°C swing between the warmest and coolest months.
