The Chatham number is from the Coast Guard station on the ocean side of the elbow whereas most reported temps are from the bay side which are warmer.
The Cape May temperature is way low. That was the first one I went looking for and got that from a Cape May site rather than the Coast Guard or NOAA readings. I found out later when I added the Wallops and Cape Charles temperatures.
60° N latitude – Greenland --------- water temp 39° F
56° N latitude – Easdale Scotland -- water temp 56° F
50° N latitude – Labrador ----------- water temp 41° F
41° N latitude - Chatham, MA ----- water temp 62° F
38° N latitude - Cape May NJ ----- water temp 63° F
37.75 N lat ---- Wallops Island ----- water temp 68° F
37.26 N lat ---- Cape Charles ------- water temp 68° F
But I read the changing climate is weakening the Gulf Stream by increasing the Labrador current and wondered what that will do to Britain....
and down the rabbit hole I went.
