Extreme Heat Watch Issued for New York City Counties

July 2, 2026 · wweather1 editorial · 2 min read

The National Weather Service (NWS) Upton NY has issued an Extreme Heat Watch for several New York City counties. This watch is active from Friday evening through Saturday evening, with dangerously hot conditions and heat index values possibly reaching up to 103.

The Extreme Heat Watch, issued by NWS Upton NY on July 1 at 11:07 PM EDT, covers Bronx, Kings (Brooklyn), New York (Manhattan), Northern Queens, Richmond (Staten Island), and Southern Queens Counties. It is in effect from 9 PM EDT Friday, July 3, through 9 PM EDT Saturday, July 4. During this period, dangerously hot conditions are possible, with heat index values up to 103.

In addition to the watch, an Extreme Heat Warning remains in effect for these areas until 9 PM EDT Friday, July 3. Conditions under this warning are described as dangerously hot, with heat index values potentially reaching up to 113.

Extreme heat and humidity significantly increase the potential for heat-related illnesses. Individuals working or participating in outdoor activities are particularly susceptible. Seniors and those with chronic health problems or mental health conditions face an increased risk. Homes without air conditioning may experience significantly hotter indoor temperatures compared to outdoor conditions.
