In reply to jhw:
In general it's cold and/or snowy in both Tuolomne and Yosemite by then, but you can get lucky--we once got 3 warm, sunny, perfect days in Yosemite in mid-November. So basically I'd say it's a wait and see the forecast type of deal.
there isn't a whole lot of HS-level stuff that I can think of though, especially single pitch/toproping. My logbook tells me I did a single pitch VS-ish route (5.8) at Church Bowl crag but I cannot for the life of me remember anything about the route or even the crag!
