Park was 2-4 cooler the prior 3 days and the coolest in the region 2 of those days.  Another 1 -2 inches of rain should add to the overgrowth and mute any 90 degree readings there till mid June while some other site get there 6/5 - 6/15.

We also have to remember that it's a park and park temperature data is not comparable to airport temperature data.

EWR: 97 (1965)

Historical:

 

1771: In Virginia, a wall of water came roaring down the James River Valley following ten to twelve days of intense rain. As water swept through Richmond, buildings, boats, animals, and vegetation were lost. About one hundred fifty people were killed as the River reached a flood stage of forty-five feet above normal. A monument to the flood was inscribed by Ryland Randolph, of Curles, in 1771-72: " ... all the great rivers of this country were swept by inundations never before experienced which changed the face of nature and left traces of violence that will remain for ages."

 

1826: A tremendous hail storm struck the eastern shore of Maryland during the evening damaging wheat and vegetable crops from Hillsborough in Caroline County to Easton in Talbot County. One person was killed. Between the Severn and Patapsco Rivers, hail the size of eggs fell. Across the bay in Calvert County, a man was killed by hail.
(Ref. Wilson Wx. History)

1896 - A massive tornado struck Saint Louis, MO, killing 306 persons and causing thirteen million dollars damage. The tornado path was short, but cut across a densely populated area. It touched down six miles west of Eads Bridge in Saint Louis and widened to a mile as it crossed into East Saint Louis. The tornado was the most destructive of record in the U.S. up until that time. It pierced a five-eighths inch thick iron sheet with a two by four inch pine plank. A brilliant display of lightning accompanied the storm. (David Ludlum) (The Weather Channel)

1973: A large F4 tornado cut a 135-mile path across central Alabama. Hardest hit was the town of Brent where five people perished and 90% of the town was demolished. Seven people died along the path of the twister. Cancelled checks from Greensboro, AL were found at Gadsden, AL, over 100 miles away. Another killer tornado struck Centerpoint on the northeast side of Birmingham, killing one person. One person was killed and 35 people were injured when an F3 tornado stormed across Jones County, Mississippi. Another 3 people were injured when an F2 tornado swept across Clarke County. A second F2 tornado also moved across Scott County that evening.
(Ref. Wilson Wx. History)

 

1987 - Severe thunderstorms in West Texas produced baseball size hail at Crane, hail up to three and a half inches in diameter at Post, and grapefruit size hail south of Midland. Five days of flooding commenced in Oklahoma. Thunderstorms produced 7 to 9 inches of rain in central Oklahoma. Oklahoma City reported 4.33 inches of rain in six hours. Up to six inches of rain caused flooding in north central Texas. (The National Weather Summary) (Storm Data)

1988 - Sunny and warm weather prevailed across much of the nation to kick off the Memorial Day weekend. Afternoon thunderstorms in southern Florida caused the mercury at Miami to dip to a record low reading of 69 degrees. (The National Weather Summary) (Storm Data)

1989 - Unseasonably hot weather prevailed in the southeastern U.S. Ten cities reported record high temperatures for the date as readings soared into the 90s. Lakeland, FL, reported a record high of 99 degrees, and Biloxi, MS, reported a temperature of 90 degrees along with a relative humidity of 75 percent. (The National Weather Summary)

1990 - Thunderstorms produced severe weather from north central Texas to the Central Gulf Coast Region. Severe thunderstorms spawned four tornadoes, and there were eighty-one reports of large hail or damaging winds. Late afternoon thunderstorms over southeast Louisiana produced high winds which injured twenty-seven persons at an outdoor music concert in Baton Rouge, and high winds which gusted to 78 mph at the Lake Ponchartrain Causeway. (Storm Data) (The National Weather Summary)

1997: An F5 tornado killed 27 people in Jarrell, Texas. Although tornado warnings were issued 30 minutes in advance and local sirens were sounded, there were few places to go for safety. Most homes were on slabs, with no basements. Houses were swept clean off their foundations, with little debris left behind. Total damage was $20 million. The same thunderstorm complex produced a wind gust to 122 mph at Kelly Air Force Base in San Antonio.

 

2001: This day brought one of the most destructive and widespread windstorms to much of Oklahoma and north Texas in recent memory. These storms left one person dead, 4 injured, 160,000 people without power and over $350 million dollars in damage in Oklahoma alone. Several non-tornadic wind reports in excess of 100 mph were recorded, and it took nearly a week to restore power to all of the affected areas

NYC: 96 (1880) record early season heatwave continued on

 

These early era heatwaves don't get talked about enough.

We also had a massive 10 day heatwave in 1896.

Central Park temps mimic an ocean facing beach town post leaf-out. 

I think @FPizz is ball busting most of the time regarding this issue. 

when you have offshore winds JFK will often be several degrees hotter than Central Park.  It's one reason why I love the south shore, we always heat up more quickly than other areas, even more than Newark, on an offshore wind.

It was joke, but no one here can take it when the temp actually lines up with other spots for 95% of the calendar days.  Too easy.

I also noticed there are days when LGA is colder than JFK in the spring and summer.  I enjoy those days.

On average JFK is a lot cooler than NYC because of its south shore-ish location. So when Central Park has temperatures comparable to a beach location you know you have a problem.

LGA is almost never cooler than JFK, maybe in the spring a little if there is a NE wind. Otherwise LGA can be 95 degrees while JFK has a south wind and low 80s. Trust me that happens all the time because I get jealous of the cooldown that doesn't reach me.

But does the park represent the concrete heat jungle of Manhattan?

South winds are the bane of my existence.  I would put up a giant wind wall along the beach if I could to keep the crap sea air away. Check out July 2010 when JFK exceeded 100 and LGA did not.

I only want west, north and northwest winds.

No it doesn't  There's another ASOS somewhere in Manhattan if I remember correctly, at the heliport, I think?

It's actually a give and take, when JFK is cooler than LGA the humidity is much higher.  It's never a free lunch.  I would much rather have 100 degrees with a 60 dew point than 80 degrees with a 75 dew point.

The main problem is measuring temperatures in a park.  New York City is nothing like a park and the airports are more representative.  If it was up to me, we'd use temperature data from downtown somewhere, there is an ASOS near the heliport.

 

I wouldn't say JFK is a lot cooler, it really depends on wind direction.  If you go further out on long island, like the Hamptons, they are a lot cooler, but where we are in SW Nassau it's not a lot cooler because we heat up faster than the city in the mornings and the wind has a much shorter trajectory over water than it does in places farther east.

Trust me, I live here and it's not a lot cooler than the city, unless you're talking about the temperatures near the subway entrances lol.

Interesting tidbits based on the above data.... 2019 (which I only remember for the heat in July), had 5 straight days of measurable snow from late February to early March followed by 14 straight days of rainfall from late April to early May. Then later in July it had the aforementioned back to back 99 degree days and the highest heat indices ever recorded at JFK (back to back 117)!

 

Also June 1949 had 0 precip.

Speaking of JFK, I remember when it hit 99 under fully overcast skies with a W or NW wind. I don’t remember what year that was but it was in the early 2010’s when I still lived in Queens, it felt so weird.

So many 99 degree days looks really weird.  There were as many 99 degree days (19) as all the 100-104 degree days combined (also 19) !!
