Here is a question for all of you blue water salts out there:

In anticipation of helping a friend deliver his boat from Tampa to Galveston in a few weeks, I have been watching he National Data Buoy Center site, http://www.ndbc.noaa.gov/ and looking at Gulf of Mexico temperatures.

It seems that the air temperature never varies more than 3 degrees from the seawater temp and therefore stays in a narrow range midday to midnight of just a few degrees. Land temperatures however vary a good 15 degrees or so.

Is this true? Or am I misreading the NDBC data? Or ?
