Were I back in the lab, I'm sure my geek friends would be up all night composing the equation that describes the water temperature change as dependent upon water depth, air temp, initial water temp, wind and other current drivers that would exchange heat, thermal effects of sunlight, and bottom composition (sand vs. mud vs. grass) as an exponential function of time. But I'm not there anymore, and can only tell you that you're right: water holds heat pretty well, and the deeper it is, the more it will resist temp change when the air above differs. Shallow water is easier to heat and cool right? Other than that, you're going to need to find some geeks...757E647F657B637878160 said:im curious to know how long the air temp needs to be cold for it to lower the temp of a water body that size enough to make a considerable difference in the fishing? its gotta take a little while right, a day or so maybe???? surley if its been 80 degrees out for two weeks and then a cold front comes in overnight dropping the air temp down to 30, the water temp should still stay reasonable warm for some amount of time?
