In most cases the average temperature is a bit lower than what your comfortable swimming temperature is. Sure it gets hotter than that some days, but pools are very slow to heat up/cool down and so they generally track the average temperature not the peak temperature. (you are probably swimming when it is peak temperature, and not at night when it is colder outside)

Yeah I suppose. I enjoy the unpreditctability outside, it's a bit of a philosophical point for me I guess, I don't want the whole world finely tuned to keep me in my comfort zone. A nice cool dip, even a little uncomfortably cool, is exilirating to me.
