Due to the length of the country, weather conditions vary by region in any given month. The central plains of Myanmar tend to experience comparatively dry conditions and can become particularly hot. In contrast, to the south of the country some areas close completely during the wet season.
The high season is generally considered to be November to February when temperatures are warm but comfortable and rainfall is at its lowest. Having said that, there is a strong argument for visiting Myanmar in the months shouldering the high season to experience fewer crowds. Generally speaking, Myanmar is considered to have two seasons – the dry season from October to May and the wet season from June to September.
Many who visit Myanmar wish to include the infamous balloon ride over Bagan. The hot air balloon rides are seasonal, from October to April, so this may be something to consider in deciding when to travel.
