Los Angeles, CA – Southern California will stay warm, sunny, and bone-dry through the middle of December as a ridge of high pressure builds over the West Coast. According to the NOAA Climate Prediction Center’s 8–14 Day Outlook, issued December 1, the region is forecast to see above-normal temperatures and below-normal precipitation from December 9 through December 15, extending the state’s ongoing dry streak.
Forecasters say highs will reach the mid to upper 70s across much of Los Angeles County, Orange County, and the Inland Empire, while San Diego and Palm Springs could push into the 80s at times. Nights will remain mild, with lows mostly in the 50s.
With below-normal rainfall, skies will stay mostly clear and humidity low — a classic setup for Santa Ana wind events and increased fire weather concerns. However, no major windstorms are currently forecast.
This mild, dry stretch reflects a strong West Coast ridge pattern, while much of the central and eastern U.S. continues to endure Arctic air and snow. The Pacific jet stream is expected to stay north of California, keeping storm systems well away through mid-December.
Forecasters don’t expect significant rain chances to return until late in the month or early January if the ridge weakens.
