Three people in New York City died during last week’s dangerous heat wave, City Hall announced Monday.
The residents were found dead in their homes over the weekend as temperatures climbed close to the triple digits, said Joe Calvello, a spokesperson for Mayor Zohran Mamdani.
“Our hearts are with their families and loved ones,” Calvello said in a statement.
Officials did not immediately release the victims’ names.
New Jersey also reported at least 22 suspected heat-related deaths, contributing to a nationwide toll that rose above two dozen, according to The Guardian.
The grim update follows New York City’s report of 21 direct heat deaths in 2025, including 19 tied to a four-day stretch of extreme heat last June.
That total was the city’s highest heat-related death count in at least 10 years and the only one during that period to reach double digits.
City Health Department data shows that more than half of New Yorkers who have died from heat inside their homes since 2016 did not have air conditioning. In the remaining cases, an air conditioner was present but either not operating or not being used.
“People who died from heat stress were most frequently exposed to heat in homes,” the city’s report said.
“Heat-exacerbated deaths were also more likely to occur at home, underscoring the importance of access to cooling at home,” the report noted.
Calvello said the report shows “why our administration undertook a massive, whole-of-government approach to respond to the extreme heat emergency: opening hundreds of cooling centers across the five boroughs, extending hours at outdoor pools, and expanding outreach to older adults, homeless New Yorkers, and others most at risk.
“This heat wave has passed, but the summer is far from over,” he said. “We will remain vigilant and continue to protect New Yorkers from the growing threat of extreme heat and other severe weather.”
The heat-wave-related deaths come just months after 19 New Yorkers died during this winter’s bitter deep freeze, with at least 15 of those fatalities directly related to hypothermia, according to the city medical examiner’s office.
Seven of the deceased died in their homes, the New York Times reported.
During the cold snap, a Post investigation found a heartbreaking 96% of pleas to help homeless New Yorkers never actually led to any assistance — with city workers even unable to find those in need at least part of the time.
From July 1 to 5 this year, the heat wave yielded more than 120 homeless-assistance requests, according to a Post analysis of 311 data, with 52 of those calls resulting in city workers unable to locate the individuals needing help.
Another 20 homeless-assistance calls saw individuals refuse help, and 25 calls were referred to other providers. Only four individuals accepted the city’s help, according to the data.
