In fact, it’s common for the days to start out cloudy and then open up in the afternoon.
Hurricane season in San Francisco
Yes, there have been earthquakes and hurricanes in California throughout history. However, this shouldn’t be a concern for tourists. There have been no natural disasters in the state for many years, and the most that can happen is a 2-3 point tremor (which is nothing serious).
If you have to go through a situation like this, look for places that have a roof and where there is no risk of items falling on you. And when you find a safe place, sit on the floor to avoid dizziness.
