November was upon Hogwarts like a great crashing wave of the ocean, the weather going from mild and dry to overcast and soggy. Heavy clouds seemed to hang right over the castle, although they held back their showers for now. Perhaps they wanted Cornish to get through his lesson, although he would hold it regardless of the weather.

They were all getting wet anyway.

The professor waited on the lake shore, dressed in flip-flops and a ratty cardigan worn over a t-shirt and board shorts. He'd built up a fire pit back from the shore, a dry place for the students to warm up while they worked. There was other bric-a-brac laying in tidy piles on the beach, nets and fish tanks and a trunk overflowing with brightly colored fabric, but noticeably nowhere to sit. These kids sat too much already.
