California Climate Zones

Welcome to GardenZeus California Climate Zones, an innovative, dynamic climate-mapping system with free search by zip code. Rather than relying on the single metric of annual low temperature or a few data points, we considered many factors including historic weather data for the entire state. With effort and iterations over years, GardenZeus distilled California's diverse climate into just 15 climate zones and assigned zones to the thousands of zip codes in California. We believe that GZ Zones provide the most accessible and useful climate-mapping system that exists for general understanding of California climate and hyper-local gardening and horticulture. Want to you know your zone? Just search by zip code.

Which climate zone are you in?

CA Zone 1: Cold Mountain Areas

The coldest high-elevation areas in California with a short growing season and winter temperatures that may drop to well below zero Fahrenheit. Lake Tahoe is the most densely populated area in this zone.
