May weather forecast
Malaysia

May ushers in the transition from the first inter-monsoon season to the Southwest Monsoon in Malaysia. As such, this month sees a slight increase in rainfall and cloud cover. The west coast of the peninsula, including cities like Kuala Lumpur, Penang, and Malacca, experiences average rainfall amounts of approximately 200mm (7.87") to 250mm (9.84"). On the other hand, the eastern regions of the peninsula and Borneo, including cities like Kuantan and Kuching, witness a further decline in precipitation, with average amounts dropping to about 200mm (7.87").

Average temperatures in May remain consistent with previous months, with a range of 26°C (78.8°F) to 32°C (89.6°F). The humid tropical heat persists across the country, making it feel hotter than the actual temperatures.

In terms of sunlight, May sees a slight decrease in average daily hours, falling to about 7 hours per day due to increased cloud cover. However, there are still significant periods of bright and sunny weather.

The Cameron Highlands, as in the previous months, continue to offer a cooler retreat from the tropical heat, with temperatures ranging between 14°C (57.2°F) to 24°C (75.2°F). Rainfall in the highlands remains substantial, with afternoon thunderstorms still a common occurrence. Visitors should be prepared for sudden weather changes, with spells of sunshine quickly shifting to heavy showers.

May serves as a prelude to the Southwest Monsoon, setting the stage for the shift in weather patterns and rainfall distribution across the country in the coming months.
