UNAM Warns Historic El Niño to Bring Heatwaves, Drought, Poor Air Quality to Mexico in 2027

UNAM researchers project that El Niño could reach historic intensity by late 2026, leading to reduced rainfall, drought, increased fires, and degraded air quality in Mexico City and beyond during 2027. The forecast is based on current climate models, but the exact intensity and regional impacts remain uncertain. This matters as it signals potential strain on water resources, agriculture, and public health in Mexico.
