Mexico extreme heat wave and regional health crises

Overview

By mid-September 2026, the health crisis in Baja California Sur continued, with 113 confirmed health cases due to extreme temperatures, including three deaths and 96 cases of heatstroke. In the neighboring state of Baja California, health authorities reported a significant rickettsia outbreak, with 53 deaths and 120 confirmed cases. The disease, transmitted via tick bites, has maintained a fatality rate of nearly 50 percent among confirmed cases, with the highest incidence in Ensenada and San Quintín.

Weather patterns in Baja California have shown a trend of more intense and dry summer days compared to previous years. While temperatures in some areas were expected to oscillate between 28 and 30 degrees Celsius, officials noted the eastern zone remains the hottest. Authorities are considering establishing hydration points in the North Zone to assist vulnerable populations, such as the homeless. In Veracruz, specifically the Veracruz-Boca del Río area, high humidity levels of approximately 70 percent have pushed the heat index to between 38 and 40 degrees Celsius, despite forecasted maximum temperatures of 33 degrees Celsius.

By September 12, the Mexican Monsoon and atmospheric instability began driving heavy rains and thunderstorms across states including Sonora, Chihuahua, Jalisco, and Michoacán. In Sonora, Hermosillo has already experienced significant flooding with accumulations exceeding 22 mm. The heat wave has also expanded to include Tamaulipas, Sinaloa, and Nuevo León, while Yucatán faces temperatures up to 37°C alongside potential showers. Intense rainfall is also expected in Baja California Sur, Durango, and Sinaloa.
