It's so hot in Florida that most cyclists don't ride after 10:00 a.m....only now is it STARTING to cool off to the 60s/70s. Winter (Florida winter, that is) is the best time to ride around here...lower humidity and less chance of heat exhaustion. I've ridden in 40-degree weather...that's about as low as I'll go. Rain doesn't stop me unless it's below 60 and/or there's thunder/lightning.
