What January feels like
January is the quietest month in the valley — you can walk into places that need a reservation in October. The vines are pruned back to sticks, the hills are green, and frost on the valley floor is real enough that growers care about it.
Expect about 6 days with real rain — enough to notice, not enough to plan around. about 9 nights dip below freezing.
