The National Weather Service has issued a Heat Advisory for New York City that will remain in effect through Wednesday.

A Heat Advisory is triggered when the combination of heat and humidity is anticipated to make it feel like 95 to 99 degrees for two or more consecutive days, or 100 to 104 degrees at any time.

The advisory is in effect until 8 p.m. Wednesday.

An Air Quality Health Advisory is also in effect for New York City through 11 p.m. Monday. 

This is the city’s second heat wave of the season, with temperatures in the low 90s, muggy conditions and increasing humidity on tap. 

Humidity levels are expected to reach tropical conditions at times, according to NY1 meteorologists.

The city’s Parks Department has extended outdoor pools hours at Olympic and intermediate-sized pools until 8 p.m. on Monday and Tuesday. Find one here.

Cooling centers throughout the city will remain open through Wednesday in preparation for the high heat.

Officials urge residents without access to air conditioning — especially senior citizens — to utilize these facilities, some of which are pet-friendly. Find one here.

The New York City Office of Emergency Management has also provided a map of outdoor cooling options, including spray showers, drinking fountains, and tree cover here. The map also details which parts of the city are the most vulnerable to extreme heat.

As temperatures climb, New Yorkers are advised to remain vigilant for symptoms of heat stroke, including hot and dry skin, elevated heart rate, confusion and nausea.

Central Park hit 95 degrees on Monday, the highest temperature in the park since Aug. 9, 2022.

Due to the heat, New Yorkers can also expect unhealthy air quality. Air pollution levels will remain high through mid-week.

By Thursday, the heat will ease a bit, and thunderstorms are expected to move through the five boroughs.
