San Luis Obispo broke a temperature record Monday, hitting 104 degrees by 2:15 p.m., according to PG&E meteorologist John Lindsey.
The previous record for Oct. 23 was 99 degrees, set in 1965, Lindsey said.
Santa Maria also broke a record. The northern Santa Barbara County city reached a high of 102 degrees Monday, compared with the previous record of 98 degrees set in 1965, Lindsey said.
It could be even hotter Tuesday, according to Lindsey, and “numerous temperature records” could be broken.
The record-breaking temperatures come as the National Weather Service has issued a heat advisory for the Central Coast that will last until 8 p.m. Tuesday.
According to the National Weather Service, temperatures in the area are forecast to range from the 90s into the 100s away from the coast. That heat, combined with gusty Santa Lucia winds and low humidity, means that the Central Coast will see extreme fire danger conditions Tuesday, according to PG&E meteorologist John Lindsey.
“This is a very unusual late season heat wave and should not be taken lightly!” the NWS wrote in its advisory report.
The agency warned that the high temperatures could cause heat illnesses and urged people who work outside, spend time outside or do not have air conditioning to take extra precautions.
Those extra measures include wearing lightweight, loose-fitting clothes, drinking plenty of water and rescheduling strenuous activities to early morning or evening, when temperatures are cooler.
The agency also reminds people not to leave people or pets in enclosed vehicles even for a short period of time, as the temperatures inside vehicles can quickly rise to life-threatening levels.
