El Niño could bring extreme heat to Mexico in 2027
UNAM specialists warn El Niño could bring extreme heat to Mexico between May and July 2027.
The climate pattern’s effects could begin in late 2026 and become strongest in the first half of 2027.
Central, southern and southeastern regions may face less rain and more heat, based partly on patterns seen in past strong El Niño events.
Those past events do not mean the same conditions will definitely happen in 2027.
Possible effects include drought, heat waves and wildfires, while parts of northwestern Mexico could see very heavy rain early in the year.
Less rain and prolonged heat could also put pressure on farming, water supplies, health and electricity use.
University and federal specialists are preparing reports to help authorities and residents plan, and they say conditions need continued monitoring.
Specialists at the National Autonomous University of Mexico warn that El Niño could bring very high temperatures to Mexico between May and July 2027.
The event could also increase heat waves and drought risk and reduce rainfall in several regions.
The effects may begin in late 2026 and reach their greatest intensity during the first half of 2027.
Past strong El Niño events point to risks in central, southern and southeastern Mexico, but the same conditions are not certain to recur.
Experts say possible impacts also include extreme rain in the northwest, wildfires and pressure on agriculture, water supplies, health and energy.
- Who
