Mexico reports heatstroke cases as temperatures climb toward 45°C

Seven heat‑stroke cases were recorded among agricultural workers in the coastal fields of Hermosillo, Sonora, with no fatalities reported. Health officials warned that the number of incidents could rise in August and September as migrant laborers arrive for the harvest season, and they urged employers to adjust work hours, provide shade and water, and train staff in first‑aid protocols.

In the northern state of Coahuila, four heat‑stroke cases have been confirmed as a heat wave pushes expected daytime highs to between 40 °C and 45 °C. The National Meteorological Service predicts the most extreme temperatures nationwide in northeastern Baja California and Sonora, where readings could exceed 45 °C. Across Mexico, the 2026 heat season (April‑June) has already generated 920 medical attendances for heat‑related illness and 30 deaths, with Tabasco, Oaxaca and Jalisco reporting the highest case numbers. Authorities recommend drinking at least two litres of water daily, avoiding prolonged sun exposure, using sunscreen and light clothing, and practicing good hygiene.
