Cooling Center Locator Phoenix & Maricopa County
Every cooling center on this page is free and open to the public. You do not need an ID, an address, money, or an appointment — walk in, cool down, and drink water for as long as the site is open.
Overheating right now? If you or someone near you has hot, dry skin, has stopped sweating, or seems confused — that is heat stroke. Call 911. Move somewhere cool and shaded while you wait.
Heat Relief Network season: the live map runs May 1 – September 30. Outside those dates, use the year-round list below or call 2-1-1.
Find the nearest open site on the live map
The Maricopa Association of Governments runs the regional Heat Relief Network — the most complete, most current map of free heat relief in the Valley, updated daily through the season.
- 200+ locations — indoor cooling centers, respite sites, and hydration stations
- Pet-friendly filter built in — find sites that welcome your animal
- Search by your location and filter by hours and services
Start from your ZIP code (optional)
If you'd rather not enter anything, that's completely fine — the map and the list below work without it. Your ZIP stays on this device and is never sent anywhere.
The most reliable sites — when the map is down or out of season
These six sites are the backbone of heat relief in Phoenix. Several run year-round; the rest run only in the May–September heat season. Hours shift week to week — when in doubt, call first or dial 2-1-1. Hours below were re-checked against each operator’s own site on November 8, 2026; where an operator publishes no winter hours, this page says so rather than guessing.
