Not bad, all things considered. About mid 50's when I left the house in what was either a light rain or a heavy fog. I got to try out my new kludged together head light (Basically a 4W LED driven by 8 AA batteries) which lit the MUP nicely. The ride home was drier (turns out it was in fact rain) but it had the typical headwinds that I know I have to deal with.
