The east coast peninsula Malaysia (Tioman Island, Terengganu & Redang Island) is now enjoying plenty of sunny dry days, along with perfect sea conditions for snorkelling and diving. Over on the west coast (Penang, Langkawi & Pangkor Islands) the south-west monsoon begins, bringing with it a rise in humidity and slightly heavier rains.
Through the centre of the peninsular and in both Kuala Lumpur and Malacca you can expect low rainfall in May although short tropical showers are likely in the afternoon. The region experiences an average temperature of 29 °C, lower in the Cameron Highlands due to the altitude at an average of 20 °C.
Its full steam ahead for the east coast destinations as they march into their peak season and embrace the minimal rainfall and perfect sea conditions for both snorkelling and diving. Visitor numbers are almost at their highest for the year, which is most noticeable at weekends (avg temp: 30 °C).
The south-west monsoon winds begin to blow over the western coastline in May bringing with them heavier afternoon thunderstorms and less than ideal sea conditions. Downpours still tend to be short-lived however and sunshine is never far behind (avg temp: 32 °C). Pangkor Island is probably the pick of the bunch weather-wise as it is a little drier (avg temp: 32 °C).
