All-time record high temps set or tied in five Bay Area cities

Nearly half a dozen Bay Area cities set or tied all-time record high temperatures Tuesday as a heat wave continued to roast the region, according to the National Weather Service.

The mercury peaked at 115 degrees in Santa Rosa and 114 in Napa, besting previous records of 113 set in 1913 and 1961, respectively, the weather service reported.

San Jose saw a high of 109, just a degree warmer than the old record set in 2017, according to the weather service.

The searing temperatures caused bus service delays in Santa Clara County, the Valley Transportation Authority reported. About 40 buses, or 10% of the agency’s normal weekday service, were pulled off routes because of heat-related mechanical failures.

Livermore and Redwood City, meanwhile, tied their previous records of 116 and 110, respectively, according to the weather service. Livermore’s record was just set Monday and Redwood City’s was set in 1972.

Livermore’s 116 is the highest ever recorded in the Bay Area.

South of the Bay Area, King City in Monterey County also set a new all-time record high temperature of 116, the weather service reported. The old record of 115 was set in 2017.
