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.
Seoul
Humid continental — hot humid summers, cold dry winters, beautiful spring and fall
Seoul has four distinct seasons. Cherry blossoms in April and autumn foliage in October rival Tokyo's. Summers bring the monsoon (jangma) and intense heat; winters are dry and bitterly cold with clear blue skies.
