Bangkok enjoys a tropical savanna climate, meaning it’s generally warm and humid throughout the year with distinct seasons influenced by the Asian monsoon system. The seasons are:
- Hot season (March to June): This is the driest and hottest time, with average highs reaching 35°C (96°F) in April. Expect sunshine and occasional summer storms.
- Rainy season (July to October): The southwest monsoon brings heavier rainfall, especially in September with an average of 336 mm (13.2 inches). Temperatures remain warm, averaging around 30°C (86°F).
- Cool season (November to February): This is the most pleasant time to visit, with dry conditions, clear skies, and comfortable temperatures between 25°C and 34°C (77°F and 93°F).
Please note:
- Bangkok experiences an urban heat island effect, meaning temperatures within the city can be several degrees higher than surrounding areas.
- Rainfall can be unpredictable, with occasional heavy downpours even outside the rainy season.
