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.
Sydney
Humid subtropical — warm summers, mild winters, year-round sunshine
Sydney enjoys one of the world's best climates. Summers are warm with beach weather; winters are mild enough for outdoor activities. The city is split between coastal suburbs (cooled by sea breezes) and inland western suburbs (dramatically hotter in summer).
