Bay Area Rainfall: When Is It Coming And When Should We Start To Worry?

Normally between Oct. 1 and mid-November, if historical averages are any guide, the Bay Area has received nearly 2 inches of rain, and Los Angeles and Fresno each have received about an inch.

But so far this year? None.

To be sure, there was one-hundredth of an inch recorded in San Jose and San Francisco — about the thickness of a few sheets of paper — over the past six weeks. But nearly every city from Sacramento to Silicon Valley to San Diego is showing lots of zeros in the rainfall column for the first two months of California’s winter rainy season.
