Is there a time when the temperature in California is below zero?

California has a long shape, and there are different climates from north to south, so we have to look at where California is before we can finally determine how cold it will be.

Because it is not given in the title, let's talk about it by region.

The overall temperature in California is livable. It is not hot in summer, and there are many places that are not cold in winter.

From Silicon Valley to the south is Southern California. Southern California has a warm climate, with four seasons like spring, no obvious winter, and the lowest 20 degrees days in the whole year are the most; Northern California has a mild climate and cool summers. There is basically snow in some places near the snowy mountain on the top of the mountain, and you can even ski in summer. But on the whole, cities and regions are cool and dry, neither cold nor snow, and the climate is suitable.

So Northern California and Southern California have their own characteristics. The coldest winter in Northern California is generally above 6 degrees Celsius, and the daily minimum temperature in winter is always above 12 degrees. That is, just wear a sweater in winter. There are many people wearing long sleeves inside and cotton-padded jackets outside, and there are more elderly people like this.

The state is dry in summer and sunny and rainy in winter. Affected by geographical conditions, the climate varies greatly. In summer, the temperature in the southeastern Colorado desert reaches 54℃, which is close to the highest temperature on the earth. In winter, the Sierra Nevada is as cold as the North Pole.

But the temperature along the Pacific coast is generally not higher than 32℃ and not lower than 0℃. The average temperatures in Los Angeles and San Francisco are 18℃ and 14℃ respectively. The precipitation in the northwest is 4420 mm, the precipitation in the southeast of Colorado desert is 50 ~ 75 mm, and the annual precipitation in the central valley is between 200 ~ 500 mm.
