Malaysian Weather Patterns
It's hot and humid year-round in Malaysia with temperatures rarely dropping below 20°C (68°F), even at night, and usually climbing to 30°C (86°F) or more during the day. The tropics can take some adjusting to so take it easy when you first arrive and avoid running around in the heat of the midday sun. Throughout the region the humidity tends to hover around the 90% mark, but on the peninsula you can always escape from heat and humidity by retreating to the delightfully cool hill stations.
The region has a monsoonal climate, but only the east coast of peninsular Malaysia has a real rainy season. The wettest season on the west coast of the peninsula is between September and December; on the east coast and in Sabah and Sarawak it's between October and February. Rain, when it comes, generally interrupts the sunshine only briefly; most of it falls in short, strong bursts. It rarely rains all day.
