The New York City Office of Emergency Management (OEM) issued another advisory this week about extreme heat that could exceed 100 degrees.
The last heat wave in 2026 occurred June 28 through July 5.
By 4 p.m., the peak of the heat wave is expected to reach 101 degrees on Friday.
The OEM advised staying hydrated, avoiding alcohol, and resting frequently.
“The air can feel heavy and your body has to work harder to stay cool so try to remain in a cooled space if possible,” the OEM Instagram advisory states.
The conditions could extend past Saturday evening if the heatwave does not break, according to forecasters.
An NWS heat advisory is only issued when the combination of heat and humidity is expected to cause 95 to 99 degree heat for two or more consecutive days, or 100 to 104 degrees for any length of time.
Senior citizens and individuals with chronic health or mental health conditions are at risk for heat-related illnesses during extreme heat conditions, such as heat stroke.
As a result, officials advise using energy wisely indoors by setting thermostats to at least 78 degrees or higher when health conditions allow.
“Turn off unnecessary lights and electronics,” the OEM said. “Delay use of washers, dryers and other high energy appliances.”
Symptoms of a heat illness can include dizziness, nausea, confusion and rapid pulse.
"The City has also dispatched Cooling Outreach On-Location (COOL) vans, they provide mobile cooling resources directed to our most vulnerable New Yorkers," OEM senior press officer Ashleigh Holmes told NTD in an Aug. 7 email. "The vans provide wellness checks, medical care, water and other supplies such as electrolytes and sunscreen, as well as transport to cooling centers or healthcare facilities."
Cooling center locations can also be found by calling 311.
