It didn't say anything about extremely hot days, though. Interestingly, NYC has a higher record highest temperature than Atlanta by a degree. Chicago has about the same number of days above 90F as NYC (17) but is a few degrees colder than NYC on average so it perhaps it has more temperature fluctations.
That whole Central Park thing throws me off, it's going to be cooler since it's a large park. The closest city Philadelphia averages 24 days above 90F, it'd be mind boggling how Philadelphia can average nearly 10 more 90F than NYC. I wish they had Newark's data.
Southern Australia is of course known for it's heatwaves, but humidity is generally low during the hottest part of the day. We had three days above 40C (108F) which is a bonafide heatwave. Hottest was about 44C.
Adelaide is ofcourse mindnumbingly hotter than Melbourne.
Adelaide gets fantastic heatwaves, while at the same time Melbourne is 10-20C cooler day and night due to constant daily cold fronts and seabreezes

They have Newark's data, though it's the airport it's here and scroll for the city. It averages 24 as well.
I usually remember Newark as having higher forecast temperatures than New York City on hot days. It's away from the coast and is still urban. The NYC Airports, the one site in Brooklyn they have and Long Island stations all have less hot days then Central Park (10-14). Poughkeepsie, in upstate about 75 miles north of Central Park, has as many hot days as Newark and Philly, too.

Measuring at Central Park is more "natural" since it is less inflated by an artificial heat island. And anyway, anywhere you put the sensor it's going to be distorted somewhat, whether it's a paved parking lot, underneath a skyscraper, at an intersection with all the vehicles and subway vents. Choosing a green location at least makes measurements more or less consistent between cities (big and small).
We occasionally get them in the Chicago area. Usually it is a few days of temperatures in the mid to upper 90s. There are usually 17 days with high temps above 90 F in Chicago.
And then there was last summer.. NYC didn't get any days above 90 until mid August in the summer, though it got two in April. Felt kinda nice in some ways, but it was too cloudy a lot of the tiem. Highest temperature in July was 86, lowest 58.
Here in Snellville, GA (right outside Atlanta) We had 43 days of 90 or above. 18 in June. 13 in July and 12 in August. However, July was 4 degrees below average (avg is 91) and August was 2 degrees below average (avg is 89). June was just 1 degree above average (avg is 88). I wonder how many days of 90+ we would have gotten if everything was average.

Below-seasonal and still had 43 days of 90+ F? Lucky!
(part of why I think I would have liked living in the southeastern US )
Our hottest summer on record had about 43 days at 86+ F;
a good summer, but I do not wish to see a summer cooler than that.
Reading all this reminds me why I like NE Wisconsin, rarely 90 where I am, I don't think I've seen one since I moved here over 2 yrs. ago! Woohoo!
Of course, if I miss them only a short drive inland will take care of it! The other day I was by the lake with jacket and a hat, 2 young men came from Green Bay with shorts, tees and flip flops, were they surprised. They said it was in the 80's in GB and I said welcome to the lake front, its 59!
Phoenix is a major city where heat waves are common occurrences. Heat is pretty much an ongiong normal event from June through September, and practically every day has high temperatures well over 100 degrees during that time of year. Phoenix is ranked as the hottest U.S. city because of the intense summer heat alone. The only thing that makes it slightly more tolerable (so they say) is the lack of humidity.
What is unusual is to have heat waves in Phoenix during the winter ... but they have happened from time to time. Both December and January had record high temperatures in the upper 80s during a couple of years, and it reached the low 90s twice on record in late February. That is very rare, however. Phoenix's winters are actually quite cool and somewhat rainy on average.
