El Niño to bring heat and drought risk across Southeast Asia

Southeast Asian nations are bracing for the effects of El Niño, which is expected to bring sustained hot and dry weather across the region in coming months. Meteorological agencies have flagged the phenomenon as a significant weather driver that will likely push temperatures higher while reducing rainfall, creating conditions ripe for drought and air quality degradation.

The warming pattern poses particular concerns for public health, with medical experts warning of a spike in heat-related ailments including heat exhaustion and heat stroke, especially among vulnerable populations such as the elderly and outdoor workers. The dry conditions are also expected to increase the risk of haze formation, particularly in areas prone to land and forest fires, further straining air quality and respiratory health across affected communities.

Governments and health agencies throughout the region have begun issuing advisories, urging residents to take precautions including staying hydrated, limiting outdoor activities during peak heat hours, and monitoring air quality indices. Agricultural sectors are also preparing for potential water stress as El Niño typically suppresses rainfall during the monsoon seasons, potentially impacting crop yields and water supplies.

Regional meteorological centres are continuing to monitor El Niño's development and intensity, with forecasts expected to guide policy responses and public health preparedness measures across Southeast Asia in the months ahead.
