Zone 14 includes the bottoms of valleys, canyons, and terrestrial watering holes in cold winter ranges from Santa Barbara County to Humboldt County. Welcome to GardenZeus California Climate Zones, an innovative and dynamic climate mapping system with free zip code search. Instead of relying on a single annual low temperature metric or a few data points, we considered many factors, including historical weather data from across the state. With effort and iterations over the years, GardenZeus summarized California's climate diversity into just 15 climate zones and assigned zones to the thousands of zip codes of California.
We believe that GZ zones provide the most accessible and useful climate mapping system that exists for the general understanding of California's climate and hyperlocal gardening and horticulture. Do you want to know your area? Just search by zip code. A place to discuss things, events and news relevant to the city of Santa Rosa, California, and Sonoma County to a lesser extent. California has a diversity of climates that has not been seen in other states, and the state provisions adopted in the California Energy Code take into account these variations using a set of sixteen climate zones.
