How will winds affect Bay Area weather this weekend?

Winds off the coast of Southern California blew the waters of the California Current, an area of ​​cold ocean water that runs along the state’s coast, and brought a southerly wave into San Francisco Bay on Thursday.

Now, a new pattern is at play, as winds from the northwest revitalize the marine layer and cause temperatures to drop. Weather models predict that temperatures will drop by 5 to 7 degrees across the interior valleys of the Gulf region, but there is a greater temperature swing. Expected for residents of coastal cities and Gulf beaches like San Francisco and Oakland. Temperatures there this weekend will drop by 10-15 degrees compared to the heat wave on Wednesday.

The sea breeze is set to blow again this weekend. Weather models predict wind gusts greater than 20 mph in the afternoon hours along the coast, Gulf Shore and Delta. Parts of the Sonoma County shoreline will likely see wind gusts up to 40 mph in the afternoon.


The strongest winds from this surge will likely hit Bodega Bay, Point Reyes in the North Bay, and a stretch of Highway 1 between Santa Cruz and Davenport, where wind speeds of up to 40 mph are possible from 1 to 7 p.m. Friday and Saturday. That will keep temperatures in the upper 60s along those stretches of the coast — about 7-10 degrees cooler than they were earlier in the week.

San Franciscans and Oaklanders can expect lighter winds of up to 30 mph and highs in the 70s, although afternoon winds of up to 35 mph are not out of the question for ferry riders.

However, a high pressure area is scheduled to reach Northern California at the end of the weekend. This may raise temperatures on Sunday by 3-5 degrees. It’s too early to tell if this will be the start of warm weather next week.
