Climate Data Historical

Malaysia has a tropical climate. The nation’s daily mean temperature is between 26-28°C, remaining fairly consistent year-round. Rainfall also remains high year-round, with approximately 3,000 mm falling each year. Two monsoon periods are perceived locally, between November-March and May-September, with the east coast of the Malaysian Peninsula, the northeast of Sabah, and southern Sarawak experiencing the most intense and prolonged periods of monsoon rainfall.

Temperature

  • Malaysia reports observed climate changes in its Second National Communication, notably a 0.6-1.2°C increase in temperatures between 1969 and 2009.
  • The fastest rates of temperature increase can be seen in the Malaysian peninsula, where the annual minimum temperature has risen 0.32°C per decade between 1969-2015.
  • Temperature rises are more pronounced during the two monsoon periods than the inter-monsoon periods (April and October).

Precipitation

  • Changes in mean annual rainfall are not significant on a national level. 
  • Significant increases in mean annual rainfall (100-200mm/yr) have been documented in the northern and western parts of the Malaysian peninsula.
  • Changes in seasonal rainfall patterns vary considerably on a sub-national level and trends are hard to identify. Significant increases in rainfall have been documented during the northeast monsoon period, particularly affecting Sabah and Sarawak.
