SAN FRANCISCO (KRON) -- The Bay Area felt unusually high temperatures to begin the week Monday and Tuesday, resulting in a number of cities breaking longstanding records, according to the National Weather Service. The hot heat that briefly held over the region was 10 to 20 degrees above normal for late March, weather officials said. Even the Bay Area coast, which is typically spared from summer heat waves, was impacted by the record-setting heat. On Monday, five locations across the East Bay and San Francisco Peninsula saw all-time highs for that date: Redwood City: 87 degrees - Previous record: 83 degrees in 1970 Half Moon Bay: 81 degrees - Previous record: 73 degrees in 1941 Oakland Museum: 84 degrees - Previous record: 75 degrees in 1997 Livermore: 84 degrees - Previous record: 82 degrees in 2022 Richmond: 78 degrees - Previous record: 78 degrees in 1951 Some of these locations, plus Napa and San Jose, again broke or tied daily records on Tuesday: Napa: 88 degrees - Previous record: 85 degrees in 1988 Richmond: 83 degrees - Tied with the record in 1952 Livermore: 90 degrees - Previous record: 82 degrees in 1997 Redwood City: 87 degrees - Previous record: 84 degrees in 1952 Oakland Downtown: 82 degrees - Previous record: 80 degrees in 1930 San Jose: 84 degrees - Tied with the record in 1930 The glimpse of summer weather was short lived, however, according to KRON4 Meteorologist Kathy Trafton. Temperatures are settling back into a more seasonal springtime range as of Wednesday, and a look ahead shows more unsettled weather is on the horizon. Banana Boat, Hawaiian Tropic sunscreens not ‘reef friendly,’ lawsuit claims Precipitation is possible for some areas on Wednesday, ranging from light rain focused on the North Bay to drizzle in coastal areas south of the Golden Gate Bridge, Trafton said. More rain from this system will arrive Thursday, with widespread light rain across the Bay Area. ...read more read less
