Where to Stay Cool in Phoenix: Cooling Centers, Hydration Stations, and Heat Relief

By Common Ladder · June 7, 2026 · 6 min read

If you're overheating, dizzy, or have stopped sweating, this is a medical emergency — call 911. To find the nearest free, air-conditioned space right now, call 2-1-1 from any phone (free, 24/7) or open the Heat Relief Network map at hrn.azmag.gov. You do not need an ID, an address, or money to walk into any cooling center in this guide.

In Phoenix, summer heat kills. Maricopa County confirmed 430 heat-related deaths in 2025 — the final count — and 49% of those who died were people experiencing homelessness. The toll has fallen two years running, from 645 in 2023 to 608 in 2024 to 430 in 2025, which is real progress and still far too many. Almost all of it is preventable. The Valley runs one of the largest heat-relief operations in the country, and every site below is free and open to the public.

The 2026 Heat Relief Network — Start Here

The Maricopa Association of Governments runs the regional Heat Relief Network from May 1 through September 30 each year. It maps more than 200 locations across the Valley: indoor cooling centers, respite sites where you can rest for hours, hydration stations handing out water, and donation drop-offs.

• Interactive map: hrn.azmag.gov — search by your location and filter for hours, services, and pet-friendly sites
• Live help: dial 2-1-1 for the nearest open site. The 211 line answers 24/7, but the operators staffing heat-relief calls (English and Spanish) work 9 a.m.–7 p.m. daily during the season — call inside that window if you can
• Ask about a ride: transportation to and from heat-relief sites is available through the network based on eligibility. If the heat is why you cannot get there, say that on the call

Hours at individual sites change week to week. The map and 211 always have the most current list — check one of them before you head out.

Downtown Phoenix: The 24/7 Respite Center

The City of Phoenix operates a 24-hour respite center at 20 W. Jackson St. in downtown Phoenix — open around the clock, every day, through the summer. It offers cooled indoor space, drinking water, and on-site navigators who can connect you to shelter, transportation, and other city services.

• Address: 20 W. Jackson St., Phoenix, AZ 85003
• Hours: Open 24 hours a day, 7 days a week
• Getting there: Walkable from downtown and on transit lines; accessible on foot, by bike, or by bus and light rail
• Know before you go: No ID required · free · open to all · water bottles welcome
• With kids? The city partners with UMOM New Day Centers on a referral basis for families with minor children who come to a 24-hour or extended-hour site — tell staff you have children with you and ask for that referral

City Cooling Centers, Hydration Stations, and Libraries

Beyond the 24/7 center, the City of Phoenix opens cooling centers and hydration stations at city facilities, and keeps select public libraries open later so people have an air-conditioned place into the evening. Libraries are free to enter — you do not need a library card to sit and cool down.

• Cholla Library (10050 N. Metro Pkwy. E.): extended hours until 9 p.m. Monday–Saturday and noon–9 p.m. on Sundays and holidays, with full library services during those hours
• Burton Barr Central Library (1221 N. Central Ave.): large downtown branch with cooling space and restrooms
• City policy at every site: no ID required, free, open to all, water encouraged

For the full, current list of city hydration stations and cooling centers with daily hours, call 2-1-1 or check the Heat Relief Network map.

Seniors 55+: The Justa Center

The Justa Center is a day center for adults age 55 and older experiencing homelessness, and it runs a cooling center and hydration station through the summer along with help getting ID, applying for benefits, meals, a nurse's clinic, and hygiene items.

• Address: 1001 W. Jefferson St., Phoenix, AZ 85007
• Cooling center / hydration: (602) 783-2175
• Main office: (602) 254-6524

• Day-center hours: opens at 7 a.m. daily and extends its hours in summer for prolonged heat relief. Published closing times vary by source, so call (602) 783-2175 to confirm today's closing time before you plan around it

St. Vincent de Paul: Day Respite, Overnight Cots, and Families

The Society of St. Vincent de Paul runs heat-relief sites across the Valley from June 1 through September 30, with cooled space, drinking water, meals, and summer survival supplies. Hours below are in addition to regular meal service.

Phoenix Dining Room (Key Campus)

• Free showers: Tuesdays, Thursdays, and Sundays, 9:30 a.m.–11:30 a.m.

Family Dining Room (families with children under 18)

• Daytime respite: 4 p.m.–6 p.m., Monday–Friday

SVdP also operates a second, 24/7 heat-relief shelter and housing program at 28th Street and Washington — but it is available by agency referral only, so do not go there directly. Ask a case manager, an outreach worker, or 211 to refer you.

St. Vincent de Paul also runs a water truck that delivers bottled water, ice, cooling towels, hats, sunscreen, and supplies for people and pets directly to encampments, mobile home communities, BLM and Trust Lands, and other high-risk areas across the Valley — on an average summer day it hands out about 400 bottles of water and 75 pounds of ice.

Know the Signs of Heat Illness

Heat exhaustion can become deadly heat stroke fast. Learn the difference:

• Heat exhaustion: heavy sweating, cold and clammy skin, weakness, nausea, dizziness, headache. Move to shade or AC, sip water, loosen clothing, cool the skin.
• Heat stroke (call 911): body feels hot but skin is dry or you've stopped sweating, confusion, slurred speech, a fast pulse, fainting, a temperature that feels dangerously high. This is life-threatening — call 911 immediately and move the person somewhere cool while you wait.

Staying Safe Between Sites

A few things that make the difference on a 110-degree day:

• Carry water and refill it everywhere — every cooling center and hydration station gives out water free
• Plan your day around the heat: be indoors from late morning through early evening, when temperatures peak
• Have a pet? Use the Heat Relief Network map's pet-friendly filter — many sites welcome animals
• If your power is about to be shut off, Arizona blocks utility disconnections during extreme heat. See our utility assistance guide for help paying the bill.
• Looking for a longer-term plan? Start the Find resources tool or build a My Ladder plan.

Start with 2-1-1 or the map at hrn.azmag.gov. Then get to the nearest cool space — it's free, and no one will ask for your ID.

Verify before you go / call ahead. Cooling-center hours and locations change throughout the season. Call 2-1-1 or check the Heat Relief Network map before traveling to any site. If a phone number is out of service, dial 211 for a current referral.
