91 now but doesn’t feel so bad with the relatively lower humidity on the west winds. Once winds go south later today it will be bad

Same here, 89.7. Upton has me topping out at 95 which I think is reasonable. Winds are currently out of the west so we have a chance. 

I’ve hit 99 twice (2018 & 2023) since I’ve lived here and both happened with the arrival of the seabreeze. Seems like the best way to briefly touch 100 out here.

Up to 92 now.

Should be a few pop storms later but the best activity is well to the north

 

The HRRR IMO is underdone somewhat while the 3km NAM is likely overdone.  The instability sort of peaks more in NJ.  We may see little to nothing on that line til the disturbance reaches far NE PA and W NJ but development would probably fire up much faster than the HRRR indicates

[bluewave]

The stronger sea breezes this summer have been keeping the ocean cooler than recent years. The upper 60s to lows 70s is refreshingly cool compared to recent summers. We can remember the numerous days with SSTs near 80° at the bouys from 2018 to 2022.

The ocean feels cold but the local harbors on the north shore are much warmer, likely upper 70s/low 80s. Been swimming in Lloyd harbor every weekend and it’s not too bad

Was in the 50s some days around the fourth of July week / weekend and last week around NJ beaches with the constant southerly flow causing persistent upwelling as the surface waters are pushed out offshore.

Shallow bays are different since they can heat up much faster than the open ocean. Plenty of upwelling along the shore this year.  The ocean near the South Shore is still warmer than the 50s down at ACY. Many days this month so far with sea breezes into the 30s and even 40s on occasion.

I would think onshore flow would make the waters warmer-usually offshore flow is what brings in the upwelling.

It’s been so strong that the waters get very choppy and enhance upwelling. Multiple times we’ve had Ambrose Jet events with gusts to 45.

Yeah, the Ambrose Jet has been so strong that JFK has had the 3rd lowest number of 90° days on record by July 15th. Only 2 days so far reaching 90°. With numerous days gusting over 30 and even 40 mph.

It's usually a safe bet that the 3km NAM is overdone, lol. That thing is INSANE.

Already up to 96 here. Looks likely that we're going to hit 100 here.

It will be a race to see how warm you can get before the Ambrose Jet kicks in later.

Topped out at 95, now down to 92, as wind shifted to the south, so I think that’s all we get. 
 

FWIW uptons point and click has me at 95 today, so it’s spot on.
