Weather in September

September signifies the transition from the Southwest Monsoon to the second inter-monsoon season in Malaysia. This period is typically characterized by increased rainfall and cloud cover compared to the preceding months. The west coast of the peninsula, including Kuala Lumpur, Penang, and Malacca, sees an increase in average rainfall, with amounts ranging from 150mm (5.91") to 200mm (7.87"). Similarly, the eastern regions of the peninsula and Borneo, including cities like Kuantan and Kuching, experience a rise in precipitation, with averages between 200mm (7.87") and 250mm (9.84").

Temperatures in September remain fairly consistent, ranging between 26°C (78.8°F) to 32°C (89.6°F). The tropical heat is ever-present, and the increase in rainfall can lead to heightened humidity levels across the country.

In terms of sunlight, September sees a slight decrease in average daily hours, with approximately 7 hours of sunshine per day. This is due to the increased cloud cover associated with the transition to the inter-monsoon season.

The Cameron Highlands, as always, provide a cooler retreat, with temperatures ranging between 14°C (57.2°F) to 24°C (75.2°F). Rainfall in the highlands is slightly higher compared to the drier months, and visitors should be prepared for more frequent afternoon showers.

September, with its increased rainfall and reduced sunlight, especially towards the end of the month, indicates the country's gradual transition into the Northeast Monsoon season. This change will bring about a significant shift in the country's weather patterns in the coming months.
