Redwood City High Temp Record Broken With 30° Drop By Friday

REDWOOD CITY, CA — The San Francisco Bay Area is showing off its swinging self this week, shifting with the whims of fall from a heat wave that broke records from Redwood City to San Jose to a cooling trough that will lower temperatures by 30 degrees in some places.

The National Weather Service reported Thursday that Redwood City's high temperature was 99 degrees on Wednesday, busting its 96-degree record set in 2016. Another city, San Jose, saw that year's record of 97 degrees topped by 2 degrees.

With that, Gilroy — known to operate hotter than most Santa Clara- and San Mateo-county cities — came in at 102 degrees. But the record 106 degrees set in 1978 is tough to beat. Gilroy often teases those high marks, a note meteorologist Scott Rowe of the Weather Service bureau in Monterey is familiar with and chuckles about.

San Francisco International Airport was the only location in the Bay Area that broke a record both Tuesday and Wednesday during this week's heat wave. With 94- and 96 degrees respectively, the records of 93- and 94 degrees from 1979 and 2016 went down.

But in fall, which kicked off the week, Bay Area temperatures are known to swing dramatically from one extreme to the next.

Friday's high in Redwood City is only supposed to reach 69 degrees, signaling a 30-degree plummet in two days.

Get out the jackets. Next thing you know it'll be snowing in the Lake Tahoe region. Wait, that's happening Sunday night.
