Super El Niño Alert: India May See 55,000 Heat-Related Deaths by March 2027

India could face a significant heat-related health challenge over the coming months, with a tracker developed by the University of Chicago’s Climate Impact Lab estimating approximately 55,000 additional heat-related deaths between October 2026 and March 2027. The projections have raised concerns about the potential impact of extreme temperatures associated with El Niño conditions. According to the tracker, March could account for a substantial share of the projected deaths. Globally, the model estimates that heat associated with El Niño could contribute to around 857,000 additional deaths during the six-month period. Nigeria, with an estimated 56,000 deaths, and India are among the countries facing the highest projected tolls, followed by Indonesia and Brazil.

Older adults, children, pregnant women, people with chronic illnesses and outdoor workers are particularly vulnerable to extreme heat. Experts emphasise the importance of early-warning systems, access to drinking water, cooling centres and adequate healthcare services to reduce the risks. However, these figures are projections generated using modelling methods and historical relationships between temperatures and mortality; they are not confirmed predictions of actual deaths. The eventual impact will depend on weather patterns, the severity and duration of heatwaves, public preparedness and the effectiveness of preventive measures. Authorities and communities can help reduce heat-related risks through timely planning and public awareness.
