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 hydration stations, refuge locations, and water donation sites throughout the Valley with the goal of preventing heat-related illnesses and deaths among vulnerable populations.
For more information about how you can avoid a heat-related illness, go to the Arizona Department of Health Services website.
In providing the content of this website for the Heat Relief Network, the Maricopa Association of Governments (MAG) has gathered substantial information from a variety of sources. MAG cannot vouch for the authenticity or accuracy of all such sources and information provided may be subject to change as well. For those reasons, users of this website should independently verify, as needed, information provided herein. To the extent that any individual has a medical emergency in regard to heat related issues, they should contact their doctor or call 911 immediately.
Partnering with MAG during the summer months gives you and your agency the opportunity to make a difference in the lives of vulnerable populations such as older adults, economically challenged residents, individuals and families who are experiencing homelessness and individuals with disabilities.
Partner roles can include providing cooling centers, hydration stations and donation collection points, or a combination of these services. It is the partner’s responsibility to ensure you have water available if you deem yourself as a cooling center and/or a hydration station location. MAG is unable to store or transport water. Please utilize the MAG Interactive Heat Relief Map to coordinate with other network partners for donations of water. We can offer assistance with navigating the interactive map when needed. There are many donation sites across the region that are willing to share donations they receive with network partners. Partners should consider participating in the Cooling Center Response Network, a decentralized donation network connecting cooling center providers with donors. We truly appreciate your partnership, together we are making a difference!
Agencies wishing to become Heat Relief Network partners must first complete the submission form to map their location. The partnering agency is responsible for coordinating with other organizations to obtain, distribute, transport, or store water and/or other donations. Donation sites are responsible for collecting donations, identifying a hydration/cooling center location to give the donations to, and for transporting the donations to the Cooling Centers or hydration stations.
Hydration only stations locations are responsible for providing water at the location identified. Cooling Centers are responsible for providing a cool place for people to take refuge from the heat. Hydration stations/Cooling Center locations may contact donation sites in search of water and coordinate directly with donation site to get water to their location.
The HRN is a voluntary partnership comprised of service providers, faith‐based groups, municipalities, businesses, and nonprofit agencies that mobilize to provide free water and heat refuge to anyone needing help in the region. Network participants can also serve as collection points for cash, bottled water, sun block, lip balm, hats, and other toiletries to combat the heat. The Network is open to any agency or organization wanting to join.
According to USClimateData.com, the average temperatures in the region during the summer months are:
May: 95 degrees
June: 104 degrees
July: 106 degrees
August: 104 degrees
September: 100 degrees.
