I avoid thunderstorms. I'm okay with wind up to the point where stuff is blowing around (max I've ridden was 45 mph gusts, and stuff was blowing, but nothing hit me). I love riding in the rain, but hate cleaning my bike afterward, so I don't usually go if it's already raining. I'm usually excited to get caught in it, though. No snow or ice for me, but every winter I think about studded tires.
