In late July 2026 Mexico faced a severe heat wave that triggered a surge in heat‑related illnesses and deaths. By July 25, authorities reported over 1,100 heat‑related cases nationwide and between 43 and 52 confirmed fatalities, with the states of Tamaulipas and Baja California experiencing the highest death tolls. Municipalities opened rehydration points and urged constant hydration.

Three days later, Chihuahua confirmed its first heatstroke death, adding to a tally of 12 heat‑related incidents in the state, including several severe cases and a child death in a vehicle. Health officials in Chihuahua reinforced warnings to avoid outdoor exposure during peak UV, stay hydrated, and keep children and pets out of cars.
