Hailstorms are rare in Malaysia, but they are not entirely absent. These events are most likely to occur during the inter-monsoon seasons, which typically span from April to May and September to October. During these periods, thunderstorms become more frequent due to shifting wind patterns and the collision of air masses from different regions. These conditions create the ideal environment for hail formation, as strong updrafts within thunderstorms allow water droplets to freeze and grow into hailstones before falling to the ground.
According to Prof. Fredolin Tangang, Chairman of the Earth Sciences & Environment Department at Universiti Kebangsaan Malaysia (UKM), hailstorms in Malaysia are often associated with strong convective storms during monsoon transitions. He also warns that climate change and rising global temperatures could increase the frequency and intensity of such events in the future. Warmer temperatures contribute to greater atmospheric instability, which can lead to more severe storms, including those capable of producing hail.
Given the potential for hail damage, homeowners in Malaysia should consider preventive measures to protect their roofs. Reinforcing roofs with impact-resistant materials, such as metal or specially designed shingles, can help mitigate damage from hailstones. Regular roof inspections and maintenance are also crucial to ensure that any vulnerabilities are addressed before a storm occurs. While hailstorms remain uncommon, taking proactive steps can safeguard properties against the unpredictable impacts of extreme weather events.
