mello-yellow:Good site (I used it before), but it does not give water temperature. What's the temp in Rhode Island or at Woods Hole?
Applicable to Cape Ann, the Boston buoy has water temp and the Sandy Bay site has water temp.
Here's NOAA's Buzzard's Bay buoy readings:

Here's the NOAA regional map of buoys:

I don't see a buoy that's close to Wood's Hole, unfortunately, but sometimes the distant buoys will show temps that correlate well to your desired area.
Here's another NOAA site showing NE coastal water temps, including Newport, RI, and Wood's Hole water temps:
