SAN FRANCISCO (KCBS Radio) -- Ask any Bay Area resident about the weather this month, and you're likely to get an earful.

May draws to a close on Friday, leaving behind a legacy of cooler-and-wetter-than-normal weather.  Official data from the National Weather Service confirm the suspicions: it was a May to forget.

Santa Rosa and Napa each recorded rainfall amounts of at least 350% of the historic May average. In Santa Rosa, that meant 4.41 inches of May rain. In Napa, 2.78 inches of rain fell in May.

While wetter than average, May 2019 was not a record-setter. San Francisco, for example, picked up 1.94 inches of May rain, making this only the 12th rainiest May since record-keeping began in the 1850's. The soggiest May ever in The City was 1925, when more than 4 inches fell.

May wasn't just damp. It was cool, too. San Jose, Santa Rosa and Livermore all registered average hourly temperatures 2.2 degrees below normal. Other Bay Area cities were closer to historic averages, but all ran below normal.
