Bangkok is buzzing whatever the weather, which tends to hit a sizzling 30°C or higher most days. If you don’t feel like dripping your way through your temple tours and sightseeing spots, avoid April to May, and September to October - the humidity can be unbearable. The hot season runs from March to June, and the rainy season from July to October (never leave the hotel without your umbrella!) and it’s ‘cooler’ than normal between November and February.
