The weather in Malaysia is great year round, though the east reaches its best between March and November. Visit Borneo between April and October for the best of the sunshine.
The weather in Malaysia is tropical without extremely high temperatures. Days are very warm, while nights are fairly cool. The main rainy season in the east runs between November and February, while August is the wettest period on the west coast.
East Malaysia has heavy rains (November to February) in Sabah and in Sarawak. However, it is difficult to generalise about the country’s climate, as rainfall differs on the east and west coasts according to the prevailing monsoon winds (northeast or southwest).
