Sonoma Wine Country's air quality reflects the Sonoma Valley's partial coastal enclosure, with vehicle traffic on CA-12 and the surrounding wine operations contributing local sources. Summer wildfire smoke from the surrounding coastal ranges is a severe and recurring seasonal concern affecting this extraordinary wine landscape, while the Petaluma Gap sea breezes provide afternoon ventilation and the valley's agricultural and forested character otherwise maintains good conditions during non-wildfire periods.
