Extreme heat expected as El Niño nears 'Super' status by year-end

Malaysia faces a high probability of experiencing a 'Super' El Niño phenomenon by the end of the year, potentially lasting into early 2027. The Malaysian Meteorological Department (METMalaysia) reports an 82% chance of El Niño beginning this month, with the likelihood increasing to 96% by year-end.

If the phenomenon reaches 'Super' status and persists for over six months, Malaysia could face significantly more extreme weather. This includes more intense heat and drought conditions, particularly starting in March next year. Such conditions were previously experienced during the 'Super' El Niño episodes of 1997/1998 and 2015/2016.

With this high probability, El Nino is expected to hit the world from the end of this year until early next year.

The current El Niño is projected to increase the risk of drought, heatwaves, and forest fires. Recent observations show rising sea surface temperatures in the central and eastern Pacific Ocean. METMalaysia Director-General Dr. Mohd Hisham Mohd Anip stated that the most significant impacts for Malaysia will be reduced rainfall and increased daily maximum temperatures, especially after El Niño peaks early next year.

The most significant impact on Malaysia is reduced rainfall and an increase in daily maximum temperatures, especially after El Nino peaks early next year.

Forecasting models suggest the upcoming Southwest Monsoon season may bring lower-than-average rainfall to many areas, particularly western and central Sarawak, eastern Sabah, and southern Peninsular Malaysia. Significant heatwaves are also possible in northern and inland Peninsular Malaysia, Sabah, and Sarawak towards the end of the Northeast Monsoon in early 2027.

In response to the potential heatwaves, geriatric medicine specialist Dr. Hakimah Sallehuddin advises the public to ensure adequate hydration, limit outdoor activities during peak heat, and wear appropriate clothing. El Niño's effects can increase the risk of heatstroke, heat exhaustion, dehydration, acute kidney injury, and muscle cramps due to mineral loss.
