Newark (interiors of NJ/se NYS/CT) Sun-Wed June 22-25 possibly hottest 3-4 day period this year (2025) with 2-4 100F+ days, possibly hottest June daily. NYC probably one 100 deg. HI exceeds 105 interior M-T June 23-24.

The clouds are putting a lid on the heat, every time it hits 104 the clouds come in and drop it to 101-102 lol.

This goes with my earlier observation that you can't have a completely cloud free 100+ day here anymore, but at least the clouds held off until after 3 PM here.

Back up to 98 at the park. I wonder if they hit 100 between hours

Did the Park hit 100 or am I delusional due to the heat?

Them and Montauk Point left

POU 100

MGJ up to 97 

[Rjay]

MMU up to 98 now

I question this cause at times it’s in the sun. But it’s back up to 98 at 4pm soooooo this can be correct 

 

stations around me were about the same

KJRB at 105 seems more accurate.

Question is, what is worse, thermometer in the shade or thermometer in the sun? Why not just average the two?

 

All official temperature readings are taken in the sun with a fan-aspirated radiation shield. Put that set up under a stand of mature trees and the temperature will drop from 3° to sometimes 5° degrees on warm sunny days.

Prior to the 1990s the sensor and shield with the fan was in direct sunlight. So this sets up the discontinuity between the pre and post 1990s temperature readings from Central Park.

This is why Newark and NYC used to trade places with which station was warmer from 1930 to 1980. It’s possible the tree growth was becoming an issue in the 80s to early 90s. But really became pronounced since the 1990s and especially since 2013.

it's like a CAT 5 cane- you need perfect conditions to maintain the strength...same thing with a high temp reading...a cloud or change in wind direction and you''re off peak

[dmillz25]

103 for the high wow

[Rjay]

Mount Pocono in the low 90s again

[SnowGoose69]

Block Island I believe hit 91 which breaks their June all time record

[cleetussnow]

JHC I just was waiting on a train platform up here and sweat beads were instant. 10 min train delay metro north.  At least the trains work.  I picked the wrong day to host a dinner in the city.  Damn.

But what I dont understand is, why do the clouds cover the sun, when there are only like 10-15 percent clouds, you'd think the sun would be unobstructed most of the time.

Does the sun somehow attract the clouds towards where it is in the sky?

On a different note, why are clouds attracted to the sun when it's extremely hot? Clouds are only 10-15% in coverage right now and yet whenever it gets to 103+ somehow the sun is a cloud magnet and the clouds cover it.... this happens every time we get to 100+ in my experience, but why?

There weren't even supposed to be any clouds today.

Sea breeze finally making a real move north

Forget the sun, it was 101-102 here even when clouds covered the sun.

It jumps to 104 as soon as the sun comes back out lol
