Heat wave spikes drownings in Spain and drives record temperatures in Mexico

In the first half of 2026 Spain recorded 217 drownings, the highest summer toll on record, with 92 deaths in June alone. The National Drowning Report (INA) linked the surge to unusually early and intense heat waves and a false sense of safety, especially on beaches where 88 victims were found, followed by pools and rivers. Experts from the Spanish Red Cross urged swimmers to use guarded beaches, follow lifeguard flags and exit the water at any sign of cramps, fatigue or dizziness.

Regional data showed Castilla y León leading interior provinces with 13 drownings, accounting for 6 % of the national total, highlighting risks in rivers, reservoirs and pools that lack the vigilance of coastal sites.

Health authorities across Europe and Mexico warned that extreme heat also drives severe heat‑related illnesses. In Spain and Mexico, elders, children and people on blood‑pressure medication are most vulnerable. Recommended measures include drinking at least 1.5 L of water daily, avoiding outdoor activity between 11 a.m. and 5 p.m., wearing light clothing, using hats and sunscreen, and seeking immediate medical help for symptoms such as dizziness, headache, fever, or loss of consciousness.

Mexico’s Sonora state experienced record temperatures, with Hermosillo reaching 47.5 °C on 23 July 2026—its highest July reading—and sensation levels of 55 °C. Authorities issued heat advisories, opened hydration stations, and urged the construction sector to shift work to cooler nighttime hours. Tamaulipas reported three heat‑related deaths, ranking third nationally, while the municipality of Cajeme declared a red alert with perceived temperatures up to 49 °C and reinforced public‑hydration campaigns.
