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.

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.

 

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.

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

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.

I love this extreme weather website, the data is easier to access and much better organized than the NWS site.

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.

Up to 72 with in between sun

12z ICON has a little powerhouse over our area:

Needed that in January

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) !!

78 and humid feeling.  Lots of puffy clouds under higher level haze looking clouds.  I can't remember the names anymore lol

Up to 75 with sun would have hit 80.

we'll get plenty of that to open up June.

even the TV mets are banging the drums for a hot start to June now.

the three month JJA forecast is out and it calls for hot weather on both the east and west coast with milder weather in the middle.

I'm excited that our forecast is rapidly changing to both hotter AND drier once June begins.  I wouldn't mind it if it didn't rain again until September.

Showers are likely tomorrow into Thursday. An additional round of showers and thundershowers is possible on Saturday. Cooler than normal temperatures will prevail through the week.

Meanwhile daily record and possible monthly record heat could develop for Friday and Saturday in such cities as Redding and Sacramento.

June looks to be warmer than normal on the CFSv2. However, just as had been the case for May, the AI guidance is notably cooler than the conventional models.

The ENSO Region 1+2 anomaly was +0.2°C and the Region 3.4 anomaly was -0.2°C for the week centered around May 21. For the past six weeks, the ENSO Region 1+2 anomaly has averaged +0.08°C and the ENSO Region 3.4 anomaly has averaged -0.08°C. Neutral ENSO conditions will likely continue through at least mid summer.

Early indications are that summer 2025 will be warmer than normal in the New York City and Philadelphia areas. The potential exists for a much warmer than normal summer (more than 1° above normal).

The SOI was +29.36 today.

The preliminary Arctic Oscillation (AO) was +2.171 today.

Based on sensitivity analysis applied to the latest guidance, there is an implied near 74% probability that New York City will have a cooler than normal May (1991-2020 normal). May will likely finish with a mean temperature near 62.7° (0.5° below normal).
