Climate and Seasons in Bangkok
Bangkok has a tropical monsoon climate and holds claim to being the hottest city in the world. Sitting at the same latitude as Khartoum and Guatemala City, it is both hot and humid in equal measure.
It may not be the warmest city in the world every day but, overall, it is unrelenting simply because it doesn't cool significantly at night. The two periods of April-May and September-October are the steamiest. The Southwest monsoons arrive between May and October and for many, this is a welcome respite.
Best Time to go to Bangkok
The best months to visit Bangkok are December to February; these make up the ‘cold months’ in which discovering the city by foot will not involve drowning perspiration. During the evenings at this time of year temperatures have been known to drop below 20 degrees Celsius.
Hottest Time in Bangkok
Bangkok's hottest time is from March through to May, when temperatures soar as high as 40 degrees. This is when the Thai New Year, Songkran takes place and the country embarks on a three-day water fight. Even though this is Thailand’s summer, the frequent bouts of rain are a welcome relief from the sweltering heat. During the ‘Hot Season’ boat cruises, mall shopping, rooftop bars and lounging by the pool come highly recommended.
Low Season (Rainy Season)
The ‘Low Season’ in Bangkok occurs between May and October. Hotels and excursions can be discounted as much as half price during this period. Although it is still hot, the city is prone to bouts of rain, which are not ideal if you've come for a beach holiday. However, the threat of rain in Bangkok is well counteracted by the long list of indoor activities including entertainment complexes, shopping, aquariums and temples. Typical characteristics of this monsoon include night rain, torrential 30-minute showers, with occasional clear skies and overcast days with little to no rain.
