Site designed and managed by Optera Creative. Zones 15 and 16 are areas of Central and Northern California that are influenced by marine air approximately 85 percent of the time and by inland air 15 percent of the time.Also worthy of note is that although Zone 16 is within the Northern California coastal climate area, its winters are milder because the areas in this zone are in thermal belts (explained on page 28). The same winter cold can damage many garden plants. Gray pines define the heart of Zone 7 around the Central Valley, but more adaptable incense cedars replace them farther north and south.
A summer afternoon wind is an integral part of this climate. ZONE 16: Central and Northern California Coast thermal belts. Typical lows in Zone 16 over a 20-year period ranged from 32 to 19°F (0 to –7°C). Because of the influence of latitude, this climate lies mostly at low elevations in Oregon’s Rogue Valley, middle elevations around California’s Central Valley, and at middle to higher elevations farther south. It’s one of Northern California’s finest horticultural climates. For example, lowland parts of Contra Coasta County are more humid than Sacramento. - Definition & Common Elements, Glencoe Chemistry - Matter And Change: Online Textbook Help, CLEP Natural Sciences: Study Guide & Test Prep, DSST Environmental Science: Study Guide & Test Prep, UExcel Anatomy & Physiology: Study Guide & Test Prep, Praxis Biology (5235): Practice & Study Guide, UExcel Earth Science: Study Guide & Test Prep, Prentice Hall Biology: Online Textbook Help, Biological and Biomedical
Lows over a 20-year period ranged from 28 to 21°F (–2 to –6°C), and record lows from 26 to 16°F (–3 to –9°C). Trees and dense shrubs planted on the windward side of a garden can disperse it, and a neighborhood full of trees can successfully keep it above the rooftops. Typical lows in Zone 16 over a 20-year period ranged from 32 to 19°F (0 to –7°C). The milder-winter, marine-influenced areas in Zone 14 and the cold-winter inland valley within Zone 14 differ in humidity. The fogs usually hug the ground at night and rise to 800 to 1,000 feet by afternoon. This benign climate exists in patches and strips along the Coast Ranges from western Santa Barbara County north to northern Marin County. The same distinction, thermal belt versus cold-air basin, determines which species and varieties—hibiscus,melaleuca, pittosporum, and other plants—are recommended for Zone 9 but not for Zone 8.
The climate pleases plants that require a marked seasonal pattern to do well—flower bulbs, peonies, lilacs, and flowering cherries, for example.

Zone 7 encompasses several thousand square miles west of the Sierra Nevada and Cascade ranges, and in the mountains that separate the Southern California coast from interior deserts. San Francisco is in northern California, where it is a popular tourist destination.
The opening in Northern California’s Coast Ranges created by San Francisco and San Pablo bays allows marine air to spill much farther inland. In Zone 9,winter lows over a 20-year period ranged from 28 to 18°F (–2 to –8°C).
The cold-winter areas that make up Zone 15 lie in cold-air basins, on hilltops above the thermal belts, or far enough north that plant performance dictates a Zone 15 designation. San Francisco, California Hardiness Zone Map.
It consists of thermal belts (slopes from which cold air drains) in the coastal climate area, which is dominated by ocean weather about 85 percent of the time and by inland weather about 15 percent. That’s a happy combination for gardening. The climate pleases plants that require a marked seasonal pattern to do well—flower bulbs, peonies, lilacs, and flowering cherries, for example. Zone 8 differs from Zone 14, which it joins near the latitudes of north Sacramento and Modesto, in that Zone 14 occasionally gets some marine influence. Answer and Explanation: Because of its location, surrounded by water, San Francisco is in a marine climate zone. This benign climate exists in patches and strips along the Coast Ranges from western Santa Barbara County north to northern Marin County. On most days and in most places, the fog tends to come in high and fast, creating a cooling and humidifying blanket between the sun and the earth, reducing the intensity of the light and sunshine. Fiercely cold, piercing north winds blow for several days at a time in winter, but they are more distressing to gardeners than to garden plants.You can minimize them with windbreaks. These areas are too high and cold in winter to be included in milder Zones 15 and 16. Fruits that need winter chill do well here, as do shrubs needing summer heat (oleander, gardenia). Only a shade of difference exists between Zone 8 and Zone 9, but it’s an important difference—crucial in some cases. Gardeners in a few spots around the San Francisco Bay will be surprised to find their gardens mapped in Zone 7. That’s a happy combination for gardening. Create your account.

In Zone 9,winter lows over a 20-year period ranged from 28 to 18°F (–2 to –8°C). For example, lowland parts of Contra Coasta County are more humid than Sacramento. The lowest recorded temperatures range from 25 to 18°F (–4 to –8°C).
