Most of Myanmar (except the mountains in the north) have a hot and humid tropical climate. Temperatures are well above 30 °C during the day and mostly around 20 °C at night. Temperatures from mid March to May can reach 40 °C and even a bit more in Mandalay, making this time rather unpleasant for visiting most places except the mountains. This time is often called the hot dry season. From June to October is rainy season. There is massive amounts of rainfall this time of year which can make travel unpleasant. At the same time most of the more popular sights will be empty and hotels will have plenty of vacancies. If someone is hardcore loner this would their time to travel. The wettest places along the coast receive a massive 1,400 mm during the wettest months. The best time to visit is during the cool dry season which is December to February. During this period there is still warm and pleasant weather. It usually is dry and rather sunny during these months. Some places even can get chilly at night, especially more inland or in the mountains. On long bus rides bring some warm cloths for the night.
