December weather forecast
Malaysia

December is well into the Northeast Monsoon season in Malaysia, a period marked by heavy rainfall, particularly in the eastern regions of the country. The west coast of the peninsula, which includes cities like Kuala Lumpur, Penang, and Malacca, experiences a slightly lower amount of rainfall compared to the previous month, with averages between 200mm (7.87") and 250mm (9.84"). However, the eastern regions of the peninsula and Borneo, including Kuantan and Kuching, continue to experience a high level of precipitation, with averages exceeding 400mm (15.75"). This continues to make December one of the wettest months of the year for these areas.

As with the rest of the year, temperatures in December remain tropical, typically ranging from 26°C (78.8°F) to 32°C (89.6°F). However, the regular rains and increased cloud cover can sometimes result in slightly cooler temperatures, particularly during the night.

Sunlight hours in December are fewer due to the prevailing weather conditions, with an average of approximately 6 hours per day.

The Cameron Highlands continue to offer a cooler alternative to the tropical heat, with temperatures ranging between 14°C (57.2°F) to 24°C (75.2°F). However, the rainfall in the highlands is also significantly high during December, with daily showers being quite common.

The heavy rainfall, increased cloud cover, and decreased sunlight hours in December, particularly in the eastern regions of Malaysia, mark the peak of the Northeast Monsoon. This weather pattern sets the stage for the transition to the drier and calmer inter-monsoon period in the coming new year.
