As temperatures continue to rise, Maricopa County is advancing its efforts to combat heat-related health issues with a comprehensive plan for 2026. The Maricopa County Department of Public Health (MCDPH) has unveiled its latest strategy aimed at reducing heat-induced illnesses and fatalities.
Significant Decline in Heat-Related Fatalities
Maricopa County has reported a notable decrease in heat-related deaths for two consecutive years. According to preliminary data, the number of deaths in 2025 was 427, a significant drop from 608 in 2024 and 645 in 2023. This reduction has been attributed in part to initiatives supported by American Rescue Plan Act (ARPA) funding, which started in the summer of 2024. Board Chair Kate Brophy McGee, District 3, stated, “This decline in heat-related deaths reflects the collective efforts of heat relief partners working together across the region.”
2026 Heat Response Strategy
The 2026 action plan emphasizes enhancing access to heat relief resources, forming stronger alliances, and raising public awareness about heat-related risks and prevention methods. Key components of the 2026 plan include:
- Intergovernmental Agreements with cities such as Phoenix, Glendale, Chandler, Mesa, and Tempe to extend the hours and accessibility of cooling and respite centers, including overnight facilities in Phoenix and Chandler.
- Partnerships with the Arizona Faith Network and other community organizations to keep more cooling centers open later and on weekends.
- Collaboration with St. Mary’s Food Bank for water storage and distribution support throughout the county.
- Enhanced call center assistance through 211 Arizona to help residents find heat relief resources, including transportation for high-risk individuals.
- Public education initiatives, bolstered by a digital billboard campaign donated by Clear Channel Outdoor, to increase awareness of heat relief resources.
- Working with community organizations to distribute educational materials, naloxone, and electrolytes at relief sites and through street outreach.
Final Year of ARPA Support
2026 marks the last year of ARPA-supported funding for these expanded heat relief measures. Dr. Nick Staab, Chief Medical Officer for MCDPH, highlighted the importance of a coordinated approach, stating, “Heat remains one of the most serious public health threats facing our community. Reducing heat-related deaths takes a coordinated response at every level.”
Community Engagement and Safety Tips
MCDPH urges residents to take necessary precautions during extreme heat conditions. While the Heat Relief Network will activate on May 1, public spaces like libraries and malls are open year-round to offer a respite from the heat. Residents are advised to stay hydrated, limit outdoor activities during peak heat, and check on those at higher risk.
Dr. Staab emphasized, “Heat deaths are preventable. By continuing to work together and staying vigilant, we can save lives.” For further information on heat safety and resources, visit Maricopa.gov/heat.
