Weather

The best overall time for visiting most of Thailand climate-wise is between November and February when it is not too wet and not too hot. The south is best visited when the rest of Thailand is miserably hot (March to May), and the north is best from mid-November to early December or when it starts warming up again in February. If you're spending time in Bangkok, be prepared to roast in April and do some wading in October - probably most challenging two months, weather-wise, in the capital.
