Malaysia could see temperatures hit 40°C next March-May

The areas most at risk are the northern states of Peninsular Malaysia, the inland areas of Kelantan and Pahang, and the interior regions of Sabah and Sarawak.

Meteorological department (MetMalaysia) director-general Hisham Anip said that based on historical records, daily maximum temperatures can exceed 38°C between March and May each year, which is typically the country’s hottest period.

“With a strong El Nino forecast and the increasingly evident effects of global warming, temperatures of around 40°C could potentially occur in Malaysia between March and May 2027,” he told Berita Harian.

El Nino refers to a natural climate event where sea surface temperatures in the central and eastern equatorial Pacific Ocean rise, leading to widespread changes in wind, pressure, and rainfall patterns globally.

It usually occurs every two to seven years and persists for about nine to 12 months.

Hisham said the areas most at risk of extreme heat in Malaysia are the northern states of Peninsular Malaysia, the inland areas of Kelantan and Pahang, and the interior regions of Sabah and Sarawak.

He warned that prolonged hot weather can have a significant impact on public health, water supply, agriculture, energy, and the environment.

Hisham said extended hot and dry weather, especially when accompanied by reduced rainfall, may lower reservoir levels and affect water supply, agriculture, industry, and hydroelectric power generation.

It also raises the risk of forest fires in peatland areas, potentially causing haze and affecting air quality and public health.

Hisham called on the public to prevent dehydration by drinking plenty of water, minimise outdoor exposure during peak heat hours, avoid open burning, and practise efficient use of water and electricity.
