Not quite sure where this line of thought started but here goes.
I line in ME
Surface water temp in the ocean currently varies for 55-65 deg.
I winter that will drop to the mid to low 30's. We may get freezing close to land.
Water down deeper is 50 degrees.
One thing that happens with tides is that on incoming tides the deeper water will upwell around anomolies such as ledge and bring the cold water to the surface.
Interestingly if you get offshore into the Gulfstream the water temp jumps into the 70's
There are web sites with the information on buoys that giver surface water temps and temps at depth for the gulf of ME and probably most of the US.
Most changes in temp in lake water occurs in the top 20 ft. Out lakes vary a lot depending on depth and whether they are spring fed. Groundwater is usually 55-60 degrees so spring fed lakes may stay on the 60's while surface water fed may be up to 80 degrees. Around here they all freeze in the winter.

In general I think there is an average temperature of surface water, but I'm wondering what kind of difference there is from warm to cold represented by the members of this group in their different locations ?
Also how much of a change with the seasons ?
Thanks for any feed back.
