The best time to visit Burma is between December and March: there is no rain and it doesn't get too hot at this time of year. The southwestern monsoon season begins between May and June and lasts until October. From March to May, the heat is practically unbearable. On the other hand, this is a good time of year to enjoy the mountains, where the climate is much cooler. The best time to explore this extraordinary country and its absolutely fascinating sites, therefore, is during the winter months. You are certain to find Burma a charming place, but avoid the really hot months.
