Umm, foggy. 72 degrees with I'd guess a 70 degree dew point. I had to sit up four or five times, to ride no handed and wipe my glasses off.
In fact, it was so foggy/humid that I had water beading on my arm hairs.
Nice morning for a ride though.
I think I've come to the conclusion that commuting three days a week is what I would call the sweet spot for me. 24 miles, round trip, three days a week puts a pretty good toll on my legs. And if I want to ride on the weekends I need a day or two off. Basically if I'm going to ride on the weekends, I'll commute three days during the week. If I know I have a weekend where I won't be able to ride, I try to commute four days.
