Living with San Andreas’ climate
What the numbers mean for a garden, a free afternoon and a bad-weather day.
Zone 9b. Frost comes about 9 winters in 10, so the growing year is set by heat, not cold: 21 days at 100° make midsummer the hard season for gardens.
Months with highs of 62–84° and lows of 40° or more: March, April, May, October and November. 0.0 miles of trails are waiting.
