I still hate dews and excessive heat, doubt you'll ever win me over on that. It's mostly dews I dislike, dry 90F is usually fun. I love the perfect outdoor weather though... those deep blue skies, 70s with long daylight. Big fan of late spring and early summer before the dews come. Honestly, this time of year may be my favorite of the year. No bugs, no mosquitoes yet, long daylight, warm afternoons, comfortable sleeping weather with no A/C.
Intermountain western US would be perfect for me. Nights in the 40s, days in the 80s all summer long at the ski towns with morning sun and afternoon scattered storms every single day for three months.
