Arroyo Grande Climate & Wine Production
The Microclimates of the Arroyo Grande Valley
Arroyo Grande Valley is a difficult AVA to generalize. The climate changes significantly in a relatively short distance. A wide range of varietals are grown in the region.
In the west, temperatures are cool and moderate. Mornings are characterized by fog, clouds, and high humidity. During summer, temperature swings are not very extreme between day and night. The weather is similar to the coastally influenced Edna Valley. Burgundian varietals, namely Pinot Noir and Chardonnay, thrive in this cool climate and exceptionally long growing season.
The eastern hills of the AVA are quite sunny and warm. Cabernet Sauvignon, Zinfandel, and Syrah are more widely planted here than the delicate grapes of Burgundy. Saucelito Canyon Vineyards is a small winery that is located in these warmer, eastern temperatures. Owners Bill and Nancy Greenough produce 1,000 cases of Estate Zinfandel each year.
