The various Sea Temperature Regions of the USA are listed above and the various seasons of the year are in the left hand coloumn (shown upon clicking a Dive Temperature Region). Not all seasons for certain temperature regions have been researched yet.

As a general guide the further north you travel in the US the lower the water temperature tends to be. The seasons play their part as well in the warming/cooling effect of the water and influence visability. The Great Lakes tend to be cool throughout the year with water temperature rarely exceeding 20 Degrees Celcius. The warmest waters lie in the Gulf of Mexico off Florida, Texas, Lousiana, Missisipi and Alabama.
