Why is California considered a region with a pleasant climate?

Coastal California

The west coast of California has warm winters, cool summers, and plenty of sunshine, making it very comfortable to live in. Many cities are options for settling, such as Los Angeles, San Francisco, San Diego, and San Jose. Even in winter, the temperature can be between 9 and 25 degrees.

Among them, San Diego has always been called "the best city in the United States" and its weather is called one of the most ideal in the world. With abundant sunshine all year round and a mild and pleasant climate, it has become a major tourist and health resort in California.
