Extreme Heat


Extreme heat kills more people than any other weather-related hazard. In 2023, the world recorded the warmest year on record. Across the United States, heat records were broken, including Phoenix, Arizona experiencing 31 consecutive days above 110°F, and Chicago, Illinois reaching a heat index of 120°F.

At HUD, increasing awareness around current and future impacts of extreme heat on the communities and people we serve is a priority. HUD is developing technical assistance resources focused on extreme heat, working on program policy updates, and coordinating with federal agency partners on extreme heat initiatives including actively participating in the National Integrated Heat Health Information System (NIHHIS).

Resources may be available to help fund investments to address extreme heat and increase climate resilience. HUD’s Build for the Future Funding Navigator can help. Search for the “resilience” project type and then the “extreme heat” project subtype to find funding opportunities that may be available.

The Office of Public & Indian Housing and Community Planning and Development has issued additional guidance on how existing HUD program resources can be used to help prepare for, respond to, and mitigate extreme heat events.
