This climate type is made up of dry, warm days, mild temperatures during most of the year, and cooler evenings. The earthquake fault rupture extended northward from the epicenter, directing much of the seismic energy toward the city of Napa. Not one – but two – mountain ranges flank the Napa Valley, providing protection from wind and weather. Save my name, email, and website in this browser for the next time I comment.
