New York, NY – Extreme heat is set to affect the Tri-State region starting Wednesday morning, with heat index values expected to surpass 100°F. The heat will persist into Thursday evening, impacting New York City, New Jersey, and southern Connecticut. A Heat Advisory has been issued from 11 a.m. Wednesday until 10 p.m. Thursday, with “feels-like” temperatures reaching 102°–103°F across Manhattan, the Bronx, Brooklyn, Queens, Staten Island, and surrounding suburbs.
Areas Affected by the Heat Advisory
The National Weather Service has warned that the heat will be particularly intense during the afternoon hours, with the heat index climbing to potentially dangerous levels. The advisory affects the following areas:
New York City (Manhattan, Bronx, Brooklyn, Queens, Staten Island)
New Jersey (Passaic, Bergen, Hudson, Essex, Union Counties)
Connecticut (Fairfield, New Haven, Middlesex, New London Counties)
Urban areas in these regions are particularly vulnerable, as dense infrastructure can trap heat, making it more difficult for temperatures to cool at night. The heat is expected to increase the risk of heat-related illnesses, especially for those without air conditioning or access to cooler spaces.
Health and Safety Precautions
Officials urge residents to take the following precautions:
Avoid strenuous outdoor activity during the hottest parts of the day.
Drink plenty of water to stay hydrated.
Check on vulnerable individuals such as the elderly, those with health conditions, and those without air conditioning.
Take advantage of cooling centers—several will be open across New York City. Residents can call 311 for more information on locations.
Outdoor workers and employers should follow OSHA guidance on providing adequate rest breaks and hydration.
Stay inside during the hottest hours and limit exposure to the heat.
Medical Emergencies: Recognizing Heat Stroke
Heat stroke is a medical emergency and requires immediate attention. Symptoms include confusion, dizziness, and fainting. If you or someone else shows signs of heat stroke, call 911 immediately.
Cooling Centers and Support
For those without air conditioning or access to cool environments, cooling centers are being set up throughout New York City to provide relief. Residents are encouraged to take advantage of these resources.
Timeline and Potential for Further Alerts
The Heat Advisory will remain in effect through Thursday night. If conditions worsen or extend, additional warnings may be issued. Residents should stay informed by monitoring local weather updates.
