Myanmar has three quite distinct seasons, although the effects of the monsoon vary in different parts of the country. The best time to visit Myanmar is the 'cool winter' season from November to February. At this time of year the weather is very pleasant - not too hot in the day and not too cool at night. In the hills it can get quite chilly in the evenings. During March, April and May the temperatures rise and will often top 100?F/40?C and it can be unpleasantly hot. The rainy season starts in May with almost daily monsoon rainfalls, mainly in the afternoons and evenings, until the rain tapers off in October.
