Northern and Central California Coast Range Thermal Belts Maritime air influences the zone much of the time, giving it cooler, moister summers than Zone 14. Typical winter lows range from 28 degrees to 21 degrees F/-2 degrees to -6 degrees C. Northern and Central California's Chilly-winter Coast-influenced Areas Mediterranean-climate plants are at home here. Periodic intrusions of marine air temper summer heat and winter cold (lows run from 26 degrees to 16 degrees F/-3 degrees to -9 degrees C). to mid-Nov., with rain coming in the remaining months. Inland Northern and Central California with Some Ocean Influence Most frosts are light (record lows run from 19 degrees to 13 degrees F/-17 degrees to -11 degrees C) scant rain comes in summer and winter. through Nov., interrupted by nearly 3 months of incandescent, growth-stopping summer heat.

Summers are cool, thanks to ocean influence chilly winters (19 degrees to -7 degrees F/-7 degrees to -22 degrees C) result from elevation, influence of continental air mass, or both. Cold-winter Western Washington and British Columbia This is fine territory for plants needing winter chill and dry, hot summers. Growing season: early May to late Sept.-shorter than in Zone 2, but offset by milder winters (lows from 13 degrees to -24 degrees F/-11 degrees to -31 degrees C). West's Mildest High-elevation and Interior Regions In northern and interior areas, lower elevations fall into Zone 2, higher areas into Zone 1. Winters are cold (lows run from -3 degrees to -34 degrees F/-19 degrees to -37 degrees C), but less so than in Zone 1. Winters are snowy and intensely cold, due to latitude, elevation, and/or influence of continental air mass.
