San Francisco has driest 2 wet seasons in 170 years | Native Information
In the two wet seasons from 2019-21, only 20.46 inches of rain fell, only second to 1975-77 when only 18.53 inches fell.
The 20.46 inches is 45% of the normal amount, which is roughly 45 inches.
“It’s been two very dry rainy seasons in a row,” said National Weather Service meteorologist Drew Peterson.
In the Bay Area, the total rainfall last season was between 39% and 41% of normal. Downtown San Francisco received 8.76 inches of rain, only 41% of normal, while San Francisco International Airport received 39% of normal.
Peterson said California generally has two to three years of rainy weather and two to three years of dry weather.
“This is a very boom or bust state,” said Peterson.
It was a little wetter in the Monterey Bay Area thanks to two new atmospheric rivers that brought rain to the area and missed most of the San Francisco Bay Area, he said.
