Peninsular Malaysia weather & when to go: September

September overview

September is a transitional month in peninsula Malaysia. The south-east monsoon and its afternoon downpours start to decline on the west coast; whilst over on the east coast the winds of the north-east monsoon begin to blow, bringing rougher sea conditions and a slight drop in temperature, although rainfall is minimal. If you're looking for beach time, the east coast is your best bet, especially at the start of the month.
