I'm a couple of months away from 60, so I checked the 60 box. No wind chill here. I rode a fixed gear century yesterday, 106 miles in almost 8 hours (6:22:26 riding time), a tad over 2,000 feet of climbing.
The temp started out at 55 deg.F at 7:30 AM and ended at 77 deg.F at 3:00 PM.
Feeling older every day, but happy to be living in SoCal.
