A suffocating heat dome will roast the Big Apple this week, with stifling humidity making it feel like 110 degrees — and electricity demands expected to hit near-record levels.

New York City is expected to suffer four straight days of sweltering 90-degree heat, with highs nearing 100 from Wednesday through Saturday as revelers gear up for the July 4 weekend.

Real-feel temperatures will hover between 105 and 110 degrees in the afternoons as scorching conditions and humidity surge, according to AccuWeather.

“It’s going to be a very intense heat wave,” Dan DePodwin, AccuWeather’s vice president of forecast operations, told The Post on Monday.

“Obviously, it’s summer and it’s hot, but this is a pretty notable heat wave because it coincides with the Fourth of July holiday and everybody being out and about. It’s important to stay well hydrated if you have to be outside, but it’s preferable to be inside.”

Temperatures will stubbornly sit between 93 to 98 degrees over the four-day spell, with readings potentially hitting or topping 100 degrees in Central Park on Thursday and Friday.

The last time Central Park hit 100 degrees was on July 18, 2012, DePodwin said.

Possible thunderstorms could strike Friday afternoon and carry into Independence Day festivities on Saturday, he added — warning revelers to have backup plans and brace for delays.

Temperatures will only drop to around 80 degrees overnight during the heat dome.

“If the low temperature is at least 80 degrees for three nights in a row, that would tie the record for most days in a row with lows equal to or greater than 80 degrees,” DePodwin said.

“This would tie the streak that we saw last year (2025) from June 23 to 25 and also ties the three-day streaks from July 2013, July 1908 and August 1896.”

The area won’t cool down until early next week, with daytime temperatures finally dipping to the mid-80s on Sunday.

DePodwin urged people to stay hydrated, check on neighbors — especially seniors, vulnerable individuals, and those without air conditioning — and stay inside when possible.

The National Weather Service has issued an extreme heat watch from noon Wednesday through 9 p.m. Friday in New York City, the Lower Hudson Valley, Long Island, northern New Jersey and western Connecticut.

Gov. Kathy Hochul said the state is also closely monitoring the heat wave and coordinating efforts involving cooling centers while monitoring the state’s electrical grid.

“This week will bring dangerous heat all across the state, and my administration is taking action to ensure New Yorkers can safely enjoy our historic summer of activities,” Hochul said in a press release.

“New Yorkers should take the proper precautions to protect themselves and their families by staying hydrated, limiting time outdoors, and monitoring your local forecast. I also encourage everyone to check in on those most vulnerable and our elderly neighbors,” she said.

The state Department of Public Service is tracking electricity systems conditions, according to Hochul’s office.

Peak baseline electricity demand is expected to reach nearly 32,000 megawatts on Thursday and 30,000 megawatts on Wednesday and Friday.

New York reached roughly last reached its record high demand of 34,000 megawatts in 2013, the New York Independent System Operator also noted.

The ISO issued an “energy warning” during a heat wave almost exactly a year ago last June, an alert one stage below an “energy emergency” when the grid operator may commence rolling blackouts.
