Meet the Heat Response Team

​Phoenix’s Office of Heat Response and Mitigation (OHRM or HeatReadyPHX) is leading the efforts of the hottest large city in the United States to fight the growing hazard of urban heat. ​OHRM focuses on both heat response (helping people cope with hot weather) and heat mitigation (cooling the city and making it more comfortable).

During all seasons of the year, HeatReadyPHX coordinates programs and policies to help lower urban temperatures and protect public health. It also tracks trends, collects data, and collaborates with other governments and organizations to share ideas and solutions when it comes to dealing with heat.​​
