Public health officials in Maricopa County are urging residents to take protective measures as heat-related deaths rise during an early and intense heat season.
As of August 22, the Maricopa County Department of Public Health had confirmed 113 heat-related deaths in 2026, with another 584 under investigation. Anyone—regardless of age, fitness level, or experience living in Arizona—can experience heat illness or death. Older adults, people with underlying medical conditions, those living in mobile homes, people experiencing homelessness, and those who use methamphetamines face elevated risk.
Dr. Nick Staab, chief medical officer for the county health department, said: "Every single heat death is preventable."
County officials recommend residents "know your risk, protect yourself, and protect others." Protective measures include staying well-hydrated, wearing lightweight clothing, and avoiding outdoor activity during peak heat hours. Once outdoor temperatures exceed 95 degrees Fahrenheit, fans cannot provide adequate cooling; residents should use air conditioning.
People can find cooling centers by calling 2-1-1 or visiting the Maricopa County Heat Relief Network map at maricopa.gov/heat.
