Will La Niña Bring Warm November Temps To CA ? See Fall Outlook

CALIFORNIA — If you’re looking forward to the chillier air that is historically typical in November, you may find it in southern California this year. An expected La Niña climate pattern promises to usher in cooler weather at the coasts and in the California mountains, more typical of fall and winter weather.

In an updated November outlook Wednesday from The Weather Channel and Atmospheric G2, November temperatures in California are expected to be at or below the normal average. Daytime temperatures at this time of year are usually in the 50s in the Southern California mountains and in the mid-20s in the evenings. At the coasts, temperatures will be blissful in the high 60s and low 70s during the day and chilly in the low 50s to mid-40s overnight. Inland SoCal will see flat 70s during the daytime, with temperatures falling into the 30s at night.

October daytime temperatures were much the same along the coasts, with warmer nights, though daytime temperatures at the mountains averaged 15 to 20 degrees warmer, according to data from The Weather Channel.

Nationally, fall temperatures have been warmer than the forecasters originally expected. The hottest November temperatures are expected in the nation’s midsection, from Minnesota to Texas and western Montana to upstate New York.

Southern California and other parts of the desert Southwest are the only places in the country expected to have near-normal to below-normal November temperatures, the National Weather Service says.

Cooler temperatures, clouds, and even rain were expected in parts of Southern California at the start of November, 2024.

Across the country, predictions for unseasonably warm temperatures lingering into December come amid mounting concern that climate change is making summers hotter and extending the warm weather well into fall.

Earlier this fall, the National Oceanic and Atmospheric Administration said it’s confident a La Niña will develop this winter but doubts it will be a strong pattern associated with consistent cold weather and heavy snowfall or other precipitation.

El Niño and La Niña are opposite phases of the El Niño-Southern Oscillation, a natural climate pattern that causes predictable changes in the tropical Pacific Ocean. They’re not the only factors in weather, but El Niño generally favors warmer, drier weather, while the opposite is true with a La Niña. Either can have an outsized effect during the winter months.

Forecasters initially expected a La Niña to develop late last winter, which was the warmest on record in the continental U.S. and worldwide.
