Redding, California – Triple-digit heat will grip Northern California starting Sunday morning, with temperatures expected to reach up to 108°F in parts of Shasta County and the Northern Sacramento Valley.
According to the National Weather Service in Sacramento, a Heat Advisory is in effect from 11 a.m. Sunday to 11 p.m. Monday, impacting areas including Redding, Shasta Dam, Red Bluff, and Paradise. Daytime highs between 102°F and 108°F are forecast, with overnight lows only dropping to the low-to-mid 70s — offering little relief.
Residents in the Northeast Foothills and Northern Sacramento Valley should avoid outdoor activity during peak afternoon hours. Heat-related illnesses are likely, especially for outdoor workers, children, the elderly, and those without reliable air conditioning.
Officials warn that rivers and lakes remain dangerously cold and fast-moving, despite the heat — increasing the risk for swimmers seeking relief. Use extreme caution near waterways.
To stay safe: limit time outdoors, drink extra fluids, wear light clothing, and check on vulnerable neighbors. Cooling centers may open in some counties — check local alerts for availability.
Heat advisories remain active through Monday evening, with additional warnings possible if high temps persist.
