Actually hot, it was 73 when I got home from work, which is warmer than I usually enjoy but comfortable, but up to 78 at 9pm when turned the ac on for an hour. Like you would expect this to happen around 3-5 pm, not 8-10. Maybe my place just has amazingly superior insulation? Or maybe amazingly shitty insulation? The south side does take the sun all day so I think it's just radiating that heat even after the outside temp goes down.
