The 2026 Heat Relief Network
The Heat Relief Network is a regional partnership of the Maricopa Association of Governments (MAG), municipalities, nonprofit organizations, the faith-based community and businesses. Each year, MAG coordinates the mapping of the Heat Relief Network, a network of partners providing water, cooling, and donation sites throughout the Valley to prevent heat-related illnesses and deaths among vulnerable populations. The map and directories are updated as new partners sign up throughout the summer season, which runs May 1 to September 30.
The region has seen a second consecutive year of decline in heat-related deaths. Maricopa County Public Health data for 2025 show 430 deaths, down from 608 in 2024 and 645 in 2023.
