KOTA KINABALU (May 7): The Southwest Monsoon is expected to begin on May 10 and continue until September, as winds start blowing consistently from the southwest toward the country. During this season, humidity levels are typically low, resulting in reduced cloud formation and less rainfall in most areas, the Meterological Department said in a statement on Wednesday.

Consequently, the country will receive lower rainfall compared to other periods, with more rainless days than rainy days.

However, heavy rain accompanied by strong winds and thunderstorms can still occur in the western Sabah, northern Sarawak, and Peninsula, particularly in the early morning due to the squall line phenomenon. A squall line is a series of thunderstorms formed by wind convergence and can persist for several hours.

During the peak of the monsoon (July to September), local and transboundary haze may occur if open burning activities are not controlled. Therefore, open burning should be avoided to reduce haze pollution that harms the country’s environment. The public is also advised to use water wisely during this period.
