September brings with it winds of change for both sides of the peninsula. The South-East monsoon and it’s afternoon downpours start to decline on the west coast (Langkawi, Penang, Pangkor) whilst over on the east coast (Tioman Island, Perhentian Islands, Terengganu, Redang) the winds of the North-East Monsoon start to blow, bringing rougher sea conditions and a slight drop in temperature. Visitor numbers will start to drop as the month progresses but the east coast will still be enjoying lots of sunny days and minimal rainfall.
Langkawi, Penang, Pangkor
The south-west monsoon continues to blow over the western coastline bringing with it heavy afternoon thunderstorms and choppy sea conditions, however, these start to decline as the month rolls on (avg temp: 30 °C).
Lowlands & Highlands
Kuala Lumpur, Malacca and Cameron Highlands
Through the centre of the peninsular and in both Kuala Lumpur and Malacca you can expect tropical downpours on most days but these rarely last longer than an hour and sunshine is never far behind (avg temp: 27 °C), lower in the Cameron Highlands due to the altitude at an average of 19 °C.
