59 degrees and foggy on the northern California coast for Memorial Day

For two or three weeks solid now it has been foggy and cold here almost non-stop here near San Francisco on the northern Coast of California. It's kind of hard to get used to and the fog (and even a little rain too) is about 20 miles inland a lot lately too so people are often complaining about the cold and wet and damp fog  both high and low along the ocean especially. When I went to the beach yesterday I had never seen so many people near the beaches where I live about 1 mile inland from all the beaches. But, I couldn't really figure out why they would come and sit in the fog at 55 to 60 degrees with a breeze off the ocean really?

But, I guess maybe they were visitors and the fog was a treat or something different for them to do?
