I don't like temp extremes of any season. If it would just stay between 65 and 75F in the summer and 40 and 55F in winter...but that ain't gonna happen. High temps are happening all over the U.S. - it was just a warm here in upstate NY this morning as it was in Miami, FL. In the southwest and southeast, they expect high heat in the summer, but not for this long and this warm for other areas.
I don't have AC, but I open doors and windows at night, but when it doesn't get much below 80F, hat doesn't help much. Fans just blow the warm air around.
