Winter is coming. When does it start getting cold in California?

Good news for Californians ready for sweater weather. In recent decades, the coldest day of the year has occurred in December for most of California.

It is according to a National Oceanic and Atmospheric Administration map which uses data from 1991 to 2020 to depict when, on average, the coldest time of year occurs in locations across the country.

While California has areas that experience their coldest day in January and beyond, experiencing the coldest day in the final month of the year is on par with the West, according to NOAA. That compares to the Midwest and East, which have their coldest days between mid-January and February.

But how cold will the coldest day in California be this year? NOAA’s Winter Outlook reported that Southern California and a central part of the state could see warmer than average temperatures for December, January and February. The rest of the state has equal chances of above, below or near average temperatures.

What day does winter start?

The first day of winter is Saturday, December 21, marked by the winter solstice.
