Call 911
Call 911 if you are experiencing or to report someone suffering from heat exhaustion.

When the heat index, which is an estimate of how it feels when air temperature and humidity are combined, is predicted to be dangerously high, New York City opens cooling centers in air-conditioned facilities to offer people relief from the heat.

Sites where cooling centers are located include:

  • Libraries
  • Community centers
  • Senior centers
  • NYCHA facilities

You should use a cooling center during a heat wave if you have no access to a cool environment, and particularly if you are at risk for heat-related illness.

Cooling center facilities are managed by New York City Agency partners, who determine each site's hours of operation and levels of accessibility. Rules and policies vary by location. Service animals are permitted at all sites.

For more information, contact a facility directly.
