What May feels like
Bike traffic on the Silverado Trail picks up and BottleRock takes over downtown Napa for a weekend, which is either the reason to come or the reason to stay away. Tasting rooms still have room to move in May; that stops being true by September.
Real rain shows up about 2 days all month; the rest stay dry.
