As a whole, the location and topography of the country generate a diversity of climate conditions. Seasonal changes in the monsoon wind directions crate summer, rainy and winter seasons. Extremes of temperature are rare.
The direction of winds and depression bring rains, and in some years severe storms occur causing damage in Rakhine region. In Rakhine and Tarintharyi regions, rain fall varies from year to year though it is always heavy and creates no hardships.
