A heat advisory covers interior Monterey County from 11 a.m. Saturday through 10 p.m. Monday, with highs reaching up to 103 degrees in the hottest spots, according to the National Weather Service.

The advisory is part of a long-duration heat wave gripping California. The Weather Service said, “Long duration heatwave expected Friday through early next week. Minimum temperatures in the low to mid 70s will provide little to no overnight relief to those without adequate cooling or hydration,” and added that “Extreme heat warnings are in effect for parts of Southern California and Heat advisories are in effect for much of Central California.”

Forecasters say the heat could linger well into October. “This is one of the longer-duration ones that I've seen in my time at this office,” National Weather Service meteorologist Rose Schoenfeld told the Los Angeles Times, adding that the heat could last until the middle of the month.

Cal/OSHA reminded employers to protect workers during the heat, with cool-down areas, rest breaks, and access to drinking water. In Monterey County, that guidance matters most in the Salinas Valley, where field crews work through the hottest hours.

Officials urge residents to drink water, wear lightweight and loose-fitting clothing, limit strenuous activities to the early morning or evening, and check on elderly relatives and neighbors during the prolonged heat.

Forecasters link the unusual stretch in part to a strong El Niño pattern and above-normal sea surface temperatures, the New York Post reported.
