Laos has the typical tropical monsoon (wet-dry) climate of the region, though the mountains provide some variations in temperature. During the rainy season (May to October), the winds of the southwest monsoon deposit an average rainfall of 50 to 90 inches (1,300 to 2,300 mm), with totals reaching some 160 inches (4,100 mm) on the Bolavens Plateau. The dry season (November to April) is dominated by the northeast monsoon. Minimum temperatures average between 60 and 70 °F (16 and 21 °C) in the cool months of December through February, increasing to highs of more than 90 °F (32 °C) in March and April, just before the start of the rains. In the wet season the average temperature is 80 °F (27 °C).
