Records for June 18 toppled in all corners of the region. San Francisco saw 88 degrees downtown, up from the 1993 record of 86. San Jose was 103 degrees, sailing past the previous record of 99 in 1945. Oakland saw a high of 97, surpassing the benchmark of 93 set in 1962.

The heat increased as a high-pressure system settled in over the Bay Area, simultaneously redirecting any cooling flow away and trapping the heat and other particles low in the atmosphere — a weather pattern typical for the Bay Area in the summer months, [National Weather Service meteorologist Charles Bell] said. The pattern also dirtied the atmosphere enough that the Bay Area Air Quality Management District issued a Spare the Air alert for Sunday, the third of the summer season.
A slight bit of moisture in the air also is trapping the heat, keeping things warm at night, Bell said.
