When is the best time to visit Bangkok? The standard answer given by most guidebooks is November-February. Whilst it’s true that the temperature and the humidity can be more bearable during Thailand’s cool season, it’s also the tourist high season and there can be distinct advantages to visiting during the rest of the year (including lower price accommodation and less crowded sightseeing).
Although the table gives a breakdown of average temperatures and rainfall in Bangkok, visitors should be aware that at times the temperature can reach as high as 40-41°C during February-May and 37-38°C the rest of the year. It’s hot and humid year round in Bangkok, but the humidity levels are at their highest from April-June.
Even during the rainy season (May-October) visitors can expect to see plenty of sunshine so don’t be put off by visiting during this time. It’s true that when the rain comes down it can be torrential and there can sometimes be flash-floods, but the downpours are often short and sharp.
