I'm generally rain-averse. Even with HiVis reflective attire and great lighting, the motorists on the road don't see well and drive too fast for conditions. The streets on my route get very slick and often flood so I can't see the pavement/debris/potholes I'm putting my tires on; and I use some low-water river crossings on my route that are completely impassible. My safety glasses fog up. Often our rains come with hail, gusting winds, or lightning.

On the other hand, a gentle summer rain can be delightful to ride in during daylight on low-traffic good streets.

My bike club has a policy of canceling rides when streets are wet. Too many cyclists have been injured, including some very experienced riders.
