The Napa Farmer’s Markets are on Tuesday and Saturday. The one on Tuesday is usually the larger one of the two (not really sure why), but it’s been a while since I’ve been there on Tuesday morning (stupid work…) It’s now held in the parking lot of Oxbow (in years past, it used to be across the street in the other parking lot).

Oxbow does have its Oxbow Farmstands which is like a mini-farmer’s market everyday, but you’re right in that the pickings are slim.
