October's heat wave breaks several California records and more are expected

An unusual October heat wave — which has yet to peak across California — has already set records across the state, causing unusually hot weather in cities across the state from Redding to San Diego.

Triple-digit temperatures in many parts of the state have left millions of Californians under heat warnings at least through Thursday — even longer in the state's desert communities near Nevada and Arizona.

“Record temperatures were reached in several locations today,” the report from the National Weather Service in Los Angeles said late Tuesday.

According to the National Weather Service, Palm Springs broke several records on Tuesday, with the high temperature of 117 degrees not only tying the daily high for Oct. 1, but also marking the highest temperature ever recorded in the city for the entire month. The city also set a record low temperature for October 1, not falling below 82 degrees even at night.

Phoenix, which suffered through a much longer heat wave, also hit a record high for any October day at 113 degrees on Tuesday.

Some daily records were set in the Central Valley on Tuesday, but highs on Wednesday and Thursday “will approach October's all-time highs,” the National Weather Service said.

These dangerously hot temperatures have increased concerns about fires and health concerns.

“Everyone is at high risk of dangerous heat illness, especially the very young, the very old, people without air conditioning and those who exercise outdoors,” the National Weather Service wrote in its heat warning for parts of the Los Angeles area. “Low nighttime temperatures provide little protection from the heat.”
