This year, Phoenix marks its first 100-degree day on April 11, ushering in a heat season characterized by extreme temperatures. With the hottest summer on record in 2024 fresh in mind, city officials are intensifying their Heat Response Plan aimed at protecting lives.

Introduced in 2022, this plan has been updated annually, focusing on the rising public health risks associated with extreme heat. The most recent update was presented to the mayor and city council on March 25, 2025.

“Our objective remains clear: to save lives. By leveraging lessons from previous years and enhancing community partnerships, we aim to increase the effectiveness of our heat response,” stated Phoenix Mayor Kate Gallego. “Phoenix faces severe heat challenges, and it’s imperative that other Valley cities take similar measures.”

This summer, 30 supply and service programs will be launched to safeguard residents, including those for first responders. In the 2024 heat season alone, the City of Phoenix Fire Department addressed over 1,400 heat-related emergency calls. Residents can explore available resources for staying cool through the Office of Heat Mitigation’s webpage: www.phoenix.gov/heat.

Respite and Cooling Centers

This year, three libraries will operate as cooling centers, with the addition of a new 24/7 respite center located at 20 W. Jackson St. Other libraries, including Cholla, Harmon, and Yucca, will extend their hours until 10 p.m. Monday through Saturday, and noon to 10 p.m. on Sundays. These centers will also provide water and heat relief supplies throughout the summer.

Hiking Restrictions

In response to safety concerns, hiking restrictions began in 2021 and were modified again in March 2025. Currently, only three trails at South Mountain Park will have specific access limitations during extreme heat warnings. Volunteers will distribute cold water and provide safety education at select trailheads on weekends from May 1 to September 30.

Summer Reading Programs

Phoenix libraries will also participate in the Maricopa County Reads program, encouraging reading among residents from June 1 to August 1. The initiative, aimed at all ages, focuses on maintaining academic skills during the summer break with various activities and prizes for participants.

City Pools

The Parks and Recreation Department operates public pools and splash pads, offering heat relief and recreational opportunities. Several pools will open for the Memorial Day weekend, with extended hours throughout the summer to provide services at no cost to eligible youth in the “Kool Kids” program.

Community Assistance

The Neighborhood Services Department ensures that rental properties comply with cooling standards, mandating acceptable temperatures. Additionally, the Human Services Department administers a utility assistance program to help residents manage energy costs.
