Page C-2 Appendix C - Climate Zone FIGURE 100.1-A—CALIFORNIA CLIMATE ZONES . The margins of all climate zones are inexact. Inland Northern and Central California with Some Ocean Influence Growing season: early Mar. To find the planting zone for California that you live in, simply find the area on the map above that you live in and match the color of that area to the map legend to the right. Natural gas is available for newly constructed buildings if a gas service line can be connected to the site without a gas m ain extension. The Köppen-Geiger climate classification is Csc. Like that of neighboring Zone 18, the climate in Zone 19 is little influenced by the ocean. The other three are Zone 7, called “Foothill-Digger Pine”; Zone 14, “Coastal Warm”; Zone 15, “Coastal Cool”; and Zone 17, “Marine.”. 4. Over a 20-year period,winter lows averaged from 22 to 17°F (–6 to –8°F).The all-time lows recorded by different weather stations in Zone 18 ranged from 22 to 7°F (–6 to –14°C). You can use Sunset’s climate maps to identify the climate characteristics of a site during the site inventory process. Because it is such a large state, California climate zones cover a wide range of temperatures. The climate here is mild, and generally warm and temperate.
