Carol was the most recent hurricane to hit Eastern LI snd SNE and still be almost purely tropical. The rapid forward motion didn’t allow for that much time north of Hatteras. Coming just after the peak SSTs of the season in late August probably helped also. http://www.ryanhanrahan.com/2013/09/01/hurricane-carol-the-monster-of-1954/ Hurricane Carol is widely viewed to be the “most tropical” of hurricanes to hit Connecticut. What’s meant by that is that while the storm was likely going extratropical transition – Carol was the most purely tropical of the storms to strike Connecticut. Here’s one example of that – take a look at this picture taken from the old Griswold Hotel in Groton near the mouth of the Thames River. The storm had a classic “eye” and the precipitation distribution from the storm – both east and west of the storm track – was relatively symmetrical. That’s very unusual for a landfalling New England hurricane!

3rd place for July 90° days at 10. The average dew point near 70° is the 2nd highest.

JFK was warmer than July 1999. But the onshore flow and 850s maxing our near +20 C kept the monthly max lower. So JFK can get a July average near 80° with onshore flow when the dew points are high and SSTs near 80°.

Pretty unusual that a local station could get a record number of 95° days without going above 97°. I guess it goes to the stuck weather patterns since 2010 allowing the maximum highs repeat in such a narrow range.

Third consecutive July with such high temperatures centered near the Northeast. People used to head for New England to beat the summer heat. Now they need to go further up into Canada for relief.

LGA was our only major station to sneak in a 100° in last July. But this is the 2nd year in a row for SNE.

That would be the highest in July since 2000 when the xmACIS2 record started. Looks like July 1999 had a 82° minimum. There was also another in August 2006.

You would really have to search for that. I just remember the old NOAA Weather Radio hourly updates with the marine reports. https://www.ndbc.noaa.gov/station_page.php?station=44025

I believe the 81° at the buoy south of Fire Island is right at the record. I can remember many years growing up when the warmest for the whole season would be around 75°. 20 S Fire Island 2150 81
