6 days of scorching temperatures over the Sound and water calm water conditions has caused the sea surface temperature to spike in a big way. Water temperatures of near or greatest than 80F are common across a large portion of the Sound. Near The Race and Fishers Island Sound, as usual, temperatures are quite a bit cooler.
This morning New Haven Harbor was at 78F (after peaking at 80F yesterday) and the Central Long Island Sound buoy was at 80F as well!
Take a look at how different the surface water temperatures are now compared to 2 weeks ago, particularly along the Jersey Shore.
