El Niño Likely to Disrupt South Asia Monsoon Season in 2026

Pakistan's Meteorological Department has issued a formal advisory warning that El Niño conditions are likely to develop during the 2026 monsoon season across South Asia, raising concerns about weather disruptions that could affect agriculture, water resources, and public health across the region.

El Niño, characterised by anomalous warming of the central and eastern Pacific Ocean, typically suppresses monsoon rainfall over South Asia, leading to below-normal precipitation, prolonged dry spells, and heightened heatwave risk. Its onset during the peak monsoon window would carry serious implications for Pakistan's rain-fed agricultural belt.

The PMD advisory places Pakistan among the most vulnerable countries in the anticipated weather pattern shift. Authorities have been urged to activate early warning protocols and strengthen drought preparedness measures, particularly in Punjab and Sindh provinces where monsoon rains are critical for kharif crop yields.

The warning comes amid a broader pattern of climate volatility in the region. Pakistan has experienced both extreme flooding and severe drought cycles in recent years, and the possible convergence of El Niño with already stressed water systems has prompted calls for accelerated climate adaptation planning at the federal and provincial levels.
