A daily 92-degree-plus heat wave is expected to roast the Big Apple for most of this week — beginning on Labor Day, with the city potentially hitting record temps, forecasters say.

The local mercury will likely peak between 92 and 94 degrees each day Monday through Thursday, Fox Weather Meteorologist Cody Braud told The Post on Sunday.  

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

“There will be a chance that some nearby cities, maybe New York, see record heat with this,” Braud said. “We could break a daily record for the high temperature.”

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

“I mean, it’s gonna be a really nice day right now,” he said. “That’s not dangerous heat by any means. You just gotta make sure you have sunscreen, take the normal precautions you would take during an average summer day.”

While the mercury might not have quite reached 90 degrees in New York City on Sunday, Michael Navarrete, 48, and Laura Pritchard, 36 – who brought their 12-month-old daughter Poppy to Central Park for an afternoon picnic – took plenty of precautions to keep their baby cool. 

“We sunscreened her whole body,” Pritchard said of Poppy, who was wearing a floral printed jumpsuit and baseball hat. “We have fans.

“The sun creeps in every 10 minutes, so we kind of have to move our spot to ensure she’s not in the sun,” the mom added. 

On hot days, the family brings “lots of water” to the Manhattan park, plus “lots of watermelon and fruits that have a lot of water content” for their little one. 

“We usually pack some sort of frozen popsicle thing,” Navarrete said. 

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

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

Told about the potentially record-breaking temps headed toward the Big Apple, the transplant said, “That’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 fashion, said she is dreading the heat wave.

“Considering the fact that this past week it got all the way down to the 60s — I’m like, ‘OK, this is amazing,’ ” she said of the weather respite. “And now, I looked at the forecast for this upcoming week, and it said 90s, and I’m like, ‘No.’

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

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

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

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

The couple booked a nice boat tour at first but then switched to a smaller craft – in hopes of getting splashed with some water to cool off. 

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

Braud said the sizzling heat is “definitely unusual” but “not unheard of” this time of year – as meteorologically, fall began Sept. 1.

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

“I think it’s just one of those things – it’s a little blip in the first couple weeks of fall and nothing more. So I don’t think we’ll have to worry about anything too extreme,” he said.

The blistering heat expected this week already swept other parts of the country last month.

“This is the same heat wave that the central part of the country and the south were experiencing for a majority of [August],” Braud said. “This big ridge – we call it a heat dome – that has been sitting over the center part of the country is gonna kind of move east the next couple days.”

It won’t be quite as hot this week as it was in late July – when intense heat bore down on the city for three days, including at least one day where the heat index made it feel like triple digits, Braud said. 

By comparison, heat indexes are only expected to go as high as 98 this week – but the scorching temps may linger for at least a day longer, according to the forecaster. 

“Don’t get me wrong, it won’t feel great outside for those couple days,” Braud said. “It’s, you know, heat that catches the city off guard the next couple days, especially since it’s been so nice.”
