San Diego is known for it’s ideal climate any time of year. But would you believe some of the best sunny summer San Diego weather happens in “winter”? It is not unusual to have sunny days with temperatures in the 70’s while the rest of the country is experiencing first snowfalls. Even in January or February, a visitor may luck out and get a few magical days in the 80’s! Sure, San Diego greets a few winter storms that roll in off the Pacific, but they are gone in a blink and serve to clean out the air and decorate the skies with clouds and gorgeous sunsets. A silver sun reflecting off the water is about as “wintery” an image as you’ll get. Pacific Beach, California.
