Unlike other AVAs in Monterey County, San Lucas is less affected by the breezes from the Monterey Bay. In the morning, this allows the fog to linger, but then results in warmer temperatures later in the day once the fog has been burned off by the afternoon sun. Temperatures often fluctuate as much as 40 degrees during the summer from day to night. This temperature swing is one of the contributing factors to the longer growing season here, giving the fruit time develop a full body and flavor.
