Myanmar has two distinct dry and wet seasons. The dry season runs from mid-October to mid-May and the rest being the wet season. During the dry season, there is a cold spell from December to February, after which warm weather sets in. The temperature in the Southern part of the country differs very little during different seasons. However, in the central plains of Myanmar seasonal temperature variations in the magnitude of 40.6° - 43.3° Celsius in hot seasons and 10°-15.6° Celsius in hot seasons are not uncommon. The northern parts of the country, on the other hand, usually experience somewhat lower temperatures throughout the year.

There also exit some cool belts in the southern tropical regions, as a result of high latitudes. Striking cases in point are Mandalay and Pyin-Oo-Lwin in central Myanmar, and Meikkhtila and Kalaw, a bit further south in the same region. A difference of about 4000 feet in latitude, within almost the same latitudes, has given rise to entirely different climatic and agro-ecological conditions, both at Pyin-Oo-Lwin and Kalaw, resulting in cooler temperatures throughout the year, and with a somewhat higher rainfall of more than 50 inches distributed evenly, over a spread of six months from May to October. On the other hand, higher latitudes remain predominant in the Chin hills and the Shan plateau, where maximum temperatures do not exceed 29.4° Celsius, and though minimum temperatures may drop as low as 7.2° Celsius.
