Climate Overview
Napa
Napa Valley's climate is world-famous for wine production — warm days, cool nights, and a reliable fog pattern. Marine air from San Francisco Bay pushes into the valley through the Carquinez Strait each evening, cooling vineyards and preventing grapes from overripening. The valley orientation from south to north creates distinct climate zones from warm Napa city to cooler Calistoga.

London's weather is famously mild but grey. It rarely gets very hot or very cold, but expect cloud cover most of the year. Summer (June–August) brings the best sunshine and warmth. Rain falls year-round but rarely in heavy bursts.
