Perfect commuting the past two days -- clear, mild temperatures and low humidity. I barely had a drop of sweat on me when I got to work today. Last week, I was drenched with sweat every day with much higher temps and humidity.
I've also been riding my Merckx Corsa more instead of my touring bike and really enjoying it for a change of pace. I'm not having to carry much clothing due to the mild temperatures and don't need my high-powered lights with the longer days, so the racing bike is fine with a large seatbag. Riding the Merckx cuts my commute time by 3-4 minutes each way and it's more fun to ride.
