A heatwave is sweeping New York this week, beginning with a possible record-breaking Labor Day fire

A daily heatwave of over 92 degrees is expected to sear the Big Apple for most of this week – beginning Labor Day, with the city potentially hitting record-breaking temperatures, forecasters say.

Local mercury is likely to peak between 92 and 94 degrees any day Monday through Thursday, Fox Weather meteorologist Cody Braud told The Post on Sunday.

While Labor Day highs are expected to be around 92 degrees, it’s possible the heat could match a record set on Sept. 4, 2018, when the thermometer read 93 degrees at LaGuardia Airport in Queens and 95 degrees at Newark Airport in New Jersey achieved, he said.

“There is a possibility that some nearby cities, maybe New York, will experience record heat as a result,” Braud said. “We could break a daily record for the high temperatures.”

But the weather expert said the heat shouldn’t keep New Yorkers from their planned holiday weekend celebrations.

“I mean, it’s going to be a really nice day now,” he said. “This is by no means dangerous heat. You just have to make sure you have sunscreen and take the usual precautions you would take on an average summer day.”

While the mercury might not have quite hit the 90-degree mark in New York City on Sunday, Michael Navarrete, 48, and Laura Pritchard, 36 – who were taking their 12-month-old daughter Poppy to Central Park for an afternoon picnic – numerous precautions to keep your baby cool.

“We put sunscreen all over her body,” Pritchard said of Poppy, who wore a floral-print jumpsuit and baseball cap. “We have fans.

“Every 10 minutes the sun comes in so we have to shift our seat to make sure it’s out of the sun,” the mum added.

On hot days, the family brings “lots of water” to Manhattan Park, as well as “lots of watermelon and fruit with a lot of water” for their little one.

“We usually pack something like frozen popsicles,” Navarrete said.

Ashley Hutchinson, 27, who works as a chef at Nougatine restaurant, was lying on a blanket in the park reading a book in the shade. She had her mini fan ready.

“I had to get this when I moved to New York,” Hutchinson, who is originally from Florida, said of her fan.

Speaking of potentially record-breaking temperatures en route to the Big Apple, the transplanter said, “It’s kind of crazy.”

“Global warming is definitely coming. We should do something about it before it gets too bad.”

Another Central Park sunbather, Madison Hoff, 22, who works in the fashion industry, said she was scared of the heatwave.

“Considering it’s been down to the 60s for the past week, I’m like, ‘Okay, that’s great,'” she said of the weather break. “And now I was looking at the forecast for the coming week and there it was in the ’90s and I was like, ‘No.’

“My body can’t sway that much,” she said.

Liz Tveten, 41, a Wisconsin tourist waiting for a boat ride on the West Side Highway near Pier 81 in Manhattan, said she brought a UV umbrella “because I knew it was going to be hot. “

“It’s the same as Wisconsin, but all I know is that New York is hot and there isn’t a lot of air conditioning,” Tveten said.

Jeremy Devoos, 33, and Franziska Glass, 32, who are visiting the city from Montreal, huddled together to have lunch under a thin strip of shade from a tiny potted tree near Pier 81.

The couple initially booked a nice boat tour but then switched to a smaller boat – hoping to cool off with some water.

“We initially wanted to cruise and then switched to the other boat because it’s refreshing to get a little bit wet,” Glass said.

Braud said the sizzling heat was “definitely unusual” but “not unusual” at this time of year — meteorologically, autumn began on September 1.

“So I wouldn’t call it rare by any means, but it does happen from time to time,” Braud said. “If you just look at the expanded forecast, you’ll quickly realize that … once we’re done with that, we’ll probably be back to more of what we’re used to.”

“I think it’s just one of those things – it’s a little blip in the first few weeks of autumn and nothing more. So I don’t think we need to worry about things that are too extreme,” he said.

The blistering heat expected for this week spread to other parts of the country last month.

“This is the same heat wave that the central part of the country and the south experienced for the most part [August]’ said Braud. “This large ridge — we call it the Heat Dome — that overlies the central part of the country is going to be moving east somehow over the next few days.”

This week won’t be quite as hot as late July – when three days of intense heat swept the city, including at least one day when the heat index felt like it was in the triple digits, Braud said.

In comparison, heat indices are expected to reach just 98 this week – but scorching temperatures could last at least a day longer, according to the weather forecaster.

“Don’t get me wrong, it’s not going to feel good outside for those few days,” Braud said. “It’s, you know, the heat that takes the city by surprise over the next few days, mostly because it’s been so beautiful.”
