When you’re commuting by bike, by the time you get from “last summer” to “today,” you’re already addicted, so the weather doesn’t matter much. (I know because I only started in September, which was after “last summer.”)
If this were in the DC area, the non-cyclist lady would also be dripping wet and really grumpy (if she were a Metro-er) or completely frazzled with her hair falling out (driver).
Even when cycling sucks, it’s so much better than the alternatives…
