The death toll from the frigid winter weather in New York City has risen to 16, Mayor Zohran Mamdani said Monday — as the blowback over his handling of the extended killer cold snap intensifies.

Hizzoner said at an unrelated press conference that 13 people died from hypothermia and another three died of overdoses outside since the freezing temps descended on the city Jan. 19.

“Each of these lives lost is a tragedy,” Mamdani said. “My heart was with the families of those mourning their loved ones.

“We are continuing to do everything in our power to get every New Yorker into a shelter where they will be warm,” he added. “ The cold is showing no signs of stopping, so neither will the city’s efforts.”

The mayor said none of the people who died were found in encampments, which his administration ordered city workers not to touch, reversing a longstanding initiative to clear shantytowns off the streets.

At least 10 of the 16 people had at one point resided in the city’s homeless shelter system, according to City Hall. 

None of them were publicly identified.

The first 10 people were found dead outside in locations across the city, between Jan. 24-27, and ranged in age at least from the mid-40s to 90, according to sources.

No information was available on the 11th fatality as of Monday. The other five were discovered in Manhattan and Brooklyn between Thursday, Jan. 29 and Sunday, 2/1, City Hall officials said. Their ages and genders were not provided.

Among them was a person found outside a building on West 207th Street in Inwood Thursday, and another in front of The Brooklyn Hospital on DeKalb Avenue and Fort Greene Place the following day.

Three other victims were found in the transit system: one was discovered Friday on the subway platform at 25th Street Station in Greenwood Heights; the second in the Port Authority Bus Terminal on Saturday and the third on a Q train at the 92nd Street Station in the Upper East Side on Sunday.

Mamdani made the grim update from the top of the David Dinkins Municipal Building — where he announced a $6 million renovation and the opening of the building for public tours come June. 

Queens Borough President Donovan Richards, who endorsed Mamdani for mayor, criticized City Hall over the weekend for not forcing people indoors during the cold snap, saying that being outside in the freezing temps amounted to a “death sentence.”

“You can’t let the people stay out there. These are people in crisis,” he said Sunday.

Mamdani pushed back on the criticism Monday, calling the prior policy a “failure.”

“It does not appear there’s any relationship between encampments and what we’ve seen with these 16 New Yorkers,” he maintained.

“We’ve said that it’s a failure because it having only connected three New Yorkers with permanent housing over the course of 365 days.”

Complaints for homeless encampments have jumped in January by nearly 60% compared to the same time last year, according to data reviewed by The Post.

Calls to 311 for the makeshift homes jumped to just over 2,050, from the 1,300 made in January 2025, public records show.
