Abundant Rainfall:
Rainfall is one of the defining features of Malaysia’s tropical climate. Malaysia receives heavy rainfall year-round, with the wettest months occurring between March and April, and again from October to November. The annual average rainfall varies across different regions of the country, ranging from 2,000 millimeters (79 inches) to over 4,000 millimeters (157 inches) in some areas. The frequent rainfall is a direct result of the country’s location near the equator and the presence of moist air currents from the surrounding oceans. -
Seasonal Variations:
Despite its tropical climate, Malaysia experiences distinct seasons that are influenced by the monsoon winds. These seasonal changes affect the amount and distribution of rainfall and temperature variations. The two main monsoon seasons that influence Malaysia are the Southwest Monsoon and the Northeast Monsoon.-
Southwest Monsoon (May to September): During this period, Malaysia experiences drier weather, especially in the west coast regions. However, the east coast, particularly on the island of Borneo, still receives substantial rainfall.
-
Northeast Monsoon (November to March): This monsoon brings more significant rainfall, particularly to the east coast of Peninsular Malaysia and the Borneo region. The monsoon often results in flooding in certain areas, especially along the coastal plains, due to the intensity and volume of rainfall.
