An upper-level, high-pressure system flowing into Los Angeles from the northeast combined with an offshore flow is expected to negate the Pacific Ocean's cooling effect.
Temperatures at the beach could reach 90.
Highs are in the upper-90s for Pasadena, Glendale, Mission Viejo, Irvine, Riverside and Ontario. Los Angeles, Woodland Hills, San Bernardino and Palm Springs could hit triple-digits.
The record high for Oct. 12 in Los Angeles was set in 1950 with a temperature of 99 degrees.
The heat is expected to continue into Thursday, according to the National Weather Service.
"Slight cooling is expected on Friday as the high-pressure system begins to weaken, with additional cooling anticipated over the weekend," according to the NWS.
