At least 10 places in the Bay Area set record-high temperatures Sunday amid an unusual October heat wave. San Francisco’s downtown reached 97 degrees, surpassing the previous Oct. 6 record of 94 set in 1992,

"We see a lot of guests coming from Sacramento, the East Bay, even the Central Valley will come up for overnight, just to get away from the heat because it's so unbearable," said Bob Partrite, CEO of Fog Harbor Fish House at Pier 39 in San Francisco.

Along the coast and the Bay, the relief was expected to begin Tuesday, with temperatures in places such as Oakland and San Mateo not exceeding 80 degrees. San Francisco, which boiled at a record 97 degrees on Sunday, is expected to have a high of 73 Tuesday and 66 on Wednesday.
