Extreme heat is NYC’s deadliest weather hazard. Air conditioning is the most effective protection against heat-related illness. Fans alone are not sufficient in high heat. If you don't have air conditioning at home, Brooklyn Public Library is proud to designate many of our branches as one of NYC's cooling centers.
New York City opens cooling centers when the National Weather Service issues a heat advisory with a forecasted heat index of:
- 95 degrees or higher for two or more days, or;
- 100 degrees for any period of time.
Be sure to check the library location's hours of operation and open status before heading out into the heat. To view a list of participating cooling centers throughout New York City, visit nyc.gov.
Cooling Centers:
- Cooling centers can be identified by a banner on the facade of the building.
- Restrooms are available; if our restrooms are not available, for whatever reason, ask library staff where the nearest accessible center is located.
- Check your branch information for accessibility status and hours of operation before traveling to a location.
- Stay informed with emergency alerts. Sign up for Notify NYC at nyc.gov/notifyNYC.
Extreme Heat Health Recommendations :
- Stay in air-conditioned spaces, especially during the hottest hours (11am–4pm).
- Drink water frequently, unless restricted by a doctor.
- Avoid strenuous activities outdoors during peak heat.
- Wear loose, light-colored clothing and apply sunscreen when outdoors.
- Never leave children, dependent adults, or pets in parked cars.
- Avoid cold showers after overheating, as they may trigger dizziness or nausea.
AIR QUALITY PREPAREDNESS - Poor air quality can pose health risks, particularly for individuals with asthma, heart or lung conditions, children, older adults, and those who work or spend extended time outdoors. To ensure the safety of our staff and patrons, branches will be supplied with and have masks readily available for distribution during air quality alerts.
