Weather Sri Lanka | Best Time to Visit Sri Lanka
Location is a tropical condition, and two major monsoons usually blow on the island. After the monsoon, come the wet and dry seasons, through which weather tends toward the south and remains dry to the north. With its small land area, its weather shows distinct regional variations, as
Southwest Monsoon (Yala): May to September. West, South, and Center are the most affected areas in the winter monsoon.
Northeast Monsoon (Maha): November to March. More or less, the Northern and Northeastern parts face northeastern direction and under the influence of the South East trade winds another phase of rains gets accumulated.
Yet regarding the climatic rounding, too much rain soaks both the side coasts, while barely any in the middle area; the area situated in the north receives plenty and much wastage runs away. On a lighter note, temperature ranges between 6°c and 30°c in the coastal areas; cool temperatures of 15°c to 18°c are experienced in the central highlands.
