Of all the cycling conditions, the only one I don't find pleasant is when it is both raining and cold.
That's because I sweat a lot. So using clothes that keep me dry from rain, usually results with being wet from sweat. When it's cold outside, I don't like being wet. Also, it requires a change of clothes when stopped - which means hauling and worrying about that as well.
Summer showers? Bring it on!
Heat, snow - all good, no problems.
