When is the 2025/2026 North-east Monsoon expected to begin and end?

Question

Accepted Answer

The 2025/2026 North-east Monsoon is forecast to commence in early November and conclude in March 2026.

The Malaysian Meteorological Department (MetMalaysia) anticipates the onset of the 2025/2026 North-east Monsoon season in early November. This period of intensified rainfall is projected to continue until March 2026. During this monsoon, an estimated five to seven episodes of heavy, continuous downpours are expected across the nation.
Initial Monsoon Impact Areas

The initial phase of the monsoon, typically from November to December 2025, is expected to primarily affect the East Coast states of Kelantan, Terengganu, and Pahang. These regions are likely to experience the most significant rainfall during this period. This forecast highlights the importance of preparedness in these specific areas as the monsoon season begins.
Subsequent Rainfall Distribution

Following the initial impact on the East Coast, the monsoon's influence is projected to shift. Johor, along with the East Malaysian states of Sabah and Sarawak, have the potential to experience episodes of continuous heavy rain. This is anticipated to occur later in the monsoon season, specifically during December 2025 and January 2026.
Enhanced Weather Monitoring Capabilities

To effectively monitor and forecast such weather events, MetMalaysia operates an extensive network of meteorological stations. This network comprises 32 main meteorological stations, 382 automatic and conventional weather stations, eight upper air stations, 18 weather radar stations, six Wind Shear Detection System stations, and three meteorological satellite receiver stations. This comprehensive system enables real-time detection of heavy rain, thunderstorms, and strong winds, thereby bolstering the country's disaster preparedness.
