Los Angeles, CA — California is poised for an unusually warm transition into 2026, with long-range forecasts indicating near-record heat across much of the state during the week of December 27 through January 2. As of Saturday, December 20, meteorologists say a dominant high-pressure ridge is expected to keep colder Pacific systems well north of the region.
According to the National Weather Service Climate Prediction Center, California falls within a broad zone favoring above-normal temperatures, a signal that spans nearly the entire western United States. This pattern often suppresses storm activity while allowing daytime temperatures to climb well above seasonal averages.
In Los Angeles, where late-December highs typically sit in the mid-60s, temperatures could rise into the low to mid-70s, approaching daily records if offshore flow develops. Inland valleys and parts of Southern California may experience even warmer conditions, while Northern California could also see mild afternoons and limited overnight cooling.
The warmth may bring short-term benefits for travel and outdoor holiday plans but raises concerns for snowpack development in the Sierra Nevada, where consistent cold is critical this time of year. Reduced precipitation and warmer temperatures could delay early-season accumulation.
Looking beyond New Year’s Day, the January 3–16, 2026 outlook continues to lean above normal across California, suggesting the mild pattern may persist into the first half of January before any meaningful cooldown arrives.
Residents are encouraged to stay updated on local forecasts, especially in fire-prone areas where dry and warm conditions can elevate seasonal risks—even during winter.
