Microclimates Thrive

In the southern portions of the Napa Valley, cool and gentle breezes make their way inland and moderate the heat of the summertime. From American Canyon to the city of Napa and beyond to Yountville, there is the wafting of breezes from the Bay. This effect makes summer days that often hit the century mark, sun-kissed yet not brutally hot. Evenings are generally cool and comfortable and invite Napa home owners and their families to stroll the streets of their tree lined towns and enjoy the bounty of local parks.

North of Yountville, the summer days are hotter because the Golden Gate breezes don’t trespass beyond the turn in the landscape. This weather, of course, is ideal for certain varietals of grapes that thrive in the heat such as Bordeaux grapes for Cabernet Sauvignon and Sauvignon Blanc. The residents of towns like St. Helena and Calistoga also bask in the warm embrace of this distinct microclimate and make the most their special place under the sun.

Napa Valley Forests

Winter rains throughout the Napa Valley tend to be moderate. The western portion, characterized by its redwood forests and shaded landscapes, gets the most rain, maintaining the lush, rich beauty of this special portion of Napa County. Throughout much of Napa County, coastal fog also moderates temperatures.

Arid and Open

On the eastern edges of Napa County is a more desert-like clime, complete with scrub brush plants and cactus. Vintners in this region take advantage of the abundant sun and special characteristics of the soils. Eastern slope exposure to the sun provides conditions similar to those in Bordeaux and Burgundy.

In just 788 square miles, Napa home owners can enjoy subtle differences within the range of a desirable Mediterranean climate – each offering perfect conditions for winemakers and people who appreciate varietals from world class appellations. It is important to note that, amid this regional variety, there are usually no extremes. Homeowners throughout Napa Valley generally enjoy a comfortable climate, no matter where their niche in the County is located.

Napa Adapts for the Future

With heightened environmental awareness, vintners and the business community consciously adapt their practices to climatic conditions. The Napa Valley Vintners even convened a task force to study the potential effects of climate change on all aspects of Napa Valley life. The group analyzed various models and looked closely at Napa Valley’s historical records. One interesting observation is that when the California’s Central Valley is at its hottest, the Napa Valley is often several degrees cooler.

The Napa Climate change Task force arrived at the conclusion that the Valley’s micro-climates make for a unique situation that is affected by the ocean and presence of fog. Already, owners of Napa Valley real estate are engaging in sustainable practices and understand they will have to adapt if conditions change over time. Growers throughout Napa County, from the giants of the industry to small farmers, are part of this unique program to prepare for a future that maintains Napa’s stature as an ideal place to both live and grow.
