HANFORD, Calif. – Central California’s run of extreme heat will begin easing this morning as a National Weather Service heat advisory expires at 8 a.m. Monday. Temperatures across the San Joaquin Valley climbed into the triple digits through the weekend, with overnight lows stuck in the 70s, providing little relief.
According to the National Weather Service in Hanford, cities including Visalia, Porterville, Hanford, Delano, and Lemoore were under the advisory, along with the Kern River Valley and west side communities like Lost Hills and Buttonwillow. Highs reached near 103 degrees on Sunday before conditions started to moderate overnight.
Officials urged residents to stay hydrated, limit outdoor activity during peak heat, and check on vulnerable neighbors. Health risks remain for those without access to cooling centers or air conditioning, as prolonged heat can trigger heat exhaustion and heat stroke.
By Monday afternoon, temperatures are expected to gradually dip below advisory criteria, though the San Joaquin Valley will still see hot and dry conditions. Cooler mornings are likely to return midweek, offering some relief after several consecutive days of dangerous heat.
Warnings have ended, but forecasters advise continued caution with lingering heat through early week.
