During the summer it is off and on. Florida weather brings heavy rain July-August from 3 until sunset, at least 4 days out of 7. Winter only gets down to upper 20s, with not as much rain, so most days there. My other factor is my running. Right now am building speed for a half marathon, so I try to time speed work with rainy days so I don’t bonk out on the ride in. The plus side is longish rides of mid effort in the evening really help loosen you up.
