The climate of San Francisco is unexpectedly cool, influenced by the cold ocean currents offshore. The city is renowned for its summer fogs, which are caused by the cold oceanic air meeting the heat from inland California. Temperatures in summer rarely exceed 71°F (22°C). Most rain falls in winter, wet days being a rarity in summer. Winter weather in San Francisco is mild but wet. The best time to visit San Francisco is during September and October, when the weather is warm and the fog less pronounced.
