Spring weather is nothing if not unpredictable. The weather can be sunny, rainy, windy, cool, or warm, or sometimes all of these things in the same day. Temperatures probably will range from the 40s to the low 60s.
Fall is usually great camping weather--mild temperatures and generally dry. Even early November, with our changing climate, is a pretty good bet these days, though it's likely to be chilly at night--you'll want a good down sleeping bag or plenty of blankets. We can't promise no rain, but our first November camp was lovely and dry with warm, sunny days, which seems to be the new normal.
There are plenty of heated indoor rooms for evening jamming -- if you're dry and warm enough in your tent to sleep, that's all you really need to do there. But we try to save dorm space for campers to upgrade to if the weather turns out to be undesirable for camping.
Do check the weather forecast, and prepare accordingly.
