Cooling Centers in Tennessee
Published:
By Marcus Webb · Southern Water Resources Editor
Tennessee summers bring sticky, oppressive heat as the humidity drives the heat index well past what the thermometer alone shows. Air conditioning is nearly universal across the state, so the greatest danger comes when severe thunderstorms knock out power and leave homes without cooling for hours or days. Cooling-center locations and hours change day to day during a heat wave, so the fastest, most reliable way to find one open right now is to call 2-1-1 — free, 24/7. We track 4 cities in Tennessee.
The dominant pattern is humid, heat-index-driven heat, so rely on air conditioning with fans and a dehumidifier rather than evaporative coolers, and keep an outage plan ready for storm season.

Where to cool off in Tennessee year-round
Even when no heat emergency is declared, these places are reliably air-conditioned and open to the public across Tennessee:
- Public libraries — the most reliable free, air-conditioned option, open to all with no purchase required, and usually with WiFi, restrooms, and water fountains.
- Shopping malls — cool, open long hours, and free to walk around.
- Community and senior centers — many double as designated cooling sites during declared heat events.
- Movie theaters and museums — reliably cold, some with free days or hours.
Call ahead to confirm hours, which vary by branch and season across Tennessee.

Frequently asked questions
Where can I find an open cooling center in Tennessee right now?
Call 2-1-1 — it's free, 24/7, and connects you to the operator who has current cooling-center data for your area.
Are Tennessee cooling centers free?
Yes. All designated cooling centers and public libraries are free and open to the public regardless of address, ID, or income.
When do Tennessee cooling centers open?
Emergency cooling centers activate when cities or counties declare a heat emergency — typically when the heat index reaches roughly 100–105°F or higher. Public libraries are air-conditioned year-round regardless.
Do evaporative "swamp" coolers work in Tennessee?
Not in Tennessee. Evaporative coolers and bowls of ice add moisture to already-humid air and make the room feel worse. Run fans, use a dehumidifier if you have one, and get to real AC during the hottest hours.
Can I bring my pet to a Tennessee cooling center?
Many cooling centers and libraries allow leashed, well-behaved pets, but policies vary by site. Call ahead using the 211 number, or check the individual site's page.
What number do I call to find a cooling center in Tennessee?
Dial 2-1-1. In some areas of Tennessee you can also text your ZIP code to 211 for a text message with nearby cooling options.
