October continues the transition between monsoon systems on both sides of the Malay Peninsula. On the West Coast of Peninsula Malaysia, the Southwest monsoon continues to dissipate although October can still see heavy afternoon thunderstorms.

Pangkor Island enjoys something of a rain shadow effect and is a good option in October.

On the East Coast on the contrary, October usually sees increasingly wet and windier weather as the Northeast monsoon begins to exert its influence and creep southwards. The beach resorts on the East Coast of Malaysia begin to wind down for the low season.

Visitor numbers to Borneo tend to drop in October, which can mean this is a good time of year to visit, with more availability at wildlife lodges and in the dive resorts.

Long sunny and dry days can be expected across much of Sabah, although rainfall does peak along the northern coast of Sabah meaning frequent short sharp afternoon showers.

Along the coastal areas of Sarawak, rainfall increases as October progresses, although much of central Sarawak remains relatively dry. This is not a bad time to visit Sarawak.
