    Water temp above ground vs in ground

    Can anyone explain how our above ground Intex in full sun all day is on average 8-10 degrees colder than neighbors in ground that only receives partial sun?

    They have solar? Running a heater?

    Over night temperatures will have a greater impact on an AGP vs IGP. The ground tends to hold heat, while the air temp can swing dramatically, which to an exposed AGP means temp drops that are much more noticeable.

    Is this really true though? Isnt the ground temp in the summer cooler than the air and in the winter warmer than the air in general? Down below the freeze line I dont think the temp varies much. Probably down in the 40s. I would think an inground pool would always be battling the ground temp.

    I would think the inground must have a heater.

    No solar no heater. Standard in ground L shape pool. My thinking was the same as Diesel, hence why my labs won't stop digging in the corners of my house to lay in the cooler dirt.
