Why is Daly City always foggy?

Daly City is not always foggy. It has a Mediterranean climate, which is characterized by mild, rainy winters and warm, dry summers. The fog that is often associated with San Francisco is caused by a combination of factors, including the cold waters of the Pacific Ocean, the prevailing wind direction, and the city's topography. Daly City is located just south of San Francisco and is not as directly affected by these factors. As a result, it experiences less fog than San Francisco.
