Ideally - you have a range of temperatures within the tank. This way the frog can seek out what works best for it.
Obviously it will be warmer at the top (lights).
It should be cooler at the bottom, but maybe a touch cooler on one side rather than the other (is the tank in question between two tanks - or is one side exposed - these things affect the inside temperature in different areas).
Some areas will be more shaded - some will be in direct light. Etc.
I don't even like to average the temps - I just want to have a decent range of choices for the frogs.
