New Yorkers are sweating out a fifth straight day of soaring temperatures with little relief in sight.
At one point today, temperature readings at JFK Airport hit 100 degrees, making this the hottest July 18th on record.
Today is also the third day that the city has endured the highest temperatures so far in the year.
A heat advisory remains in effect until midnight, but will be upgraded to a heat warning Friday.
Cooling centers were open Thursday, though it's not clear whether they will be open again Friday.
In Coney Island, some residents got their exercise in early while others squeezed in some chill time, just before it got too crowded and too hot.
"It's a pattern of laying in the sun, going in the water, laying in the sun, going in the water," said one beachgoer.
Those who have become regulars at a cooling center on 12th Street say they have settled into a comfy routine.
"I can walk in here. It's easier. And in this day and age I look for the easy thing," said Sylvan Rantzer, a Coney Island resident.
"It keeps me out of that hot sun out there and off the boardwalk," said another Coney Island resident.
Staying indoors may get even more important for children and those with breathing problems as the day goes on.
State officials are warning that the amount of ozone will increase in the late afternoon and mid-evening hours of Thursday. There is an air quality health alert in effect until 11 o'
Meantime, residents over the age of 18 who want to open a hydrant can pick up an FDNY approved spray cap at any local firehouse.

With the dog days of summer clearly in effect, residents are reminded to keep their four-legged friends safe as well.
The head of the Alliance for New York City's Animals recommends a few tips to keep your pet cool.
For instance, they recommend pouring water over a dog's coat, paws and the outside of their ears before going for a walk.
Animal care officials say owners should bring extra water along and limit the time pets are outside.
Asphalt and concrete can retain heat and burn their paws.
Officials warn if a dog is panting heavily, has a bright red tongue, or vomits to bring him or her inside and call a vet.
Cat owners should also make sure their pets can handle the heat by keeping fresh water for them and making sure window screens are secure so they do not fall out.
