Where is the place with foggest days each year?

The place with the foggiest days in the world is San Francisco, California, United States. Due to its unique geographic location at the meeting point of the Pacific Ocean and the San Francisco Bay, as well as the influence of cold ocean currents, it experiences frequent fog conditions. These fogs, locally known as Karl or summer fog, typically appear in the late afternoon/evening and burn off by the afternoon. While other coastal cities around the world may also experience heavy fog, San Francisco stands out as one of the foggiest cities yearly with persistent daily occurrence of its renowned Karl fog.
