In addition, several islands are part of the urban area, including Treasure Island, Yerba Buena Island and the infamous Alcatraz. One of the most recognizable features of the city are the 43 rolling hills on which the city is built, as well as the beautiful Victorian houses and cable cars that characterize them.

The metropolis is considered the 13th most populous city in the United States and the fourth largest city in California. In 2007, the city population was 764,976, with the San Fran Bay Area consisting of more than 7.1 million people.

The area of ​​the city is approximately 121 square kilometers, with the interior of the city limits often referred to as “seven by seven miles square”.

San Francisco, which is both a city and a county, has one form of government. The mayor, who acts as general manager, is elected for four years, as are the eleven members of the city council.

Climate in San Francisco

California has a Mediterranean climate with mild, humid winters and dry summers. San Francisco is surrounded by water on three sides, which greatly affects its climate and makes it milder than neighboring California cities with little seasonal temperature fluctuations. The average summer temperatures are between 15 and 24 ° C and in winter between 10 and 15 degrees Celsius.

The city’s temperature will almost never drop below freezing. A common saying is that San Francisco has three seasons: winter, summer, and fog. The combination of cold sea water and the high heat of mainland California makes for misty conditions in spring and early summer. The eastern quarters are a little less foggy because of the hills that separate the ocean air from the mainland temperature. This side of San Francisco has an average of 260 clear days per year.

When is the best time to visit San Francisco?

The best time to visit San Francisco is from May through October. However, it should be noted that the good weather conditions in summer naturally also attract a large number of tourists (from abroad and within the country). Especially in July and August, San Francisco is often packed, it is the absolute peak season.

Between December and March the temperatures are often cool and rainfalls occur regularly, which is why winter is not a preferred time to travel to San Francisco. However, the peripheral months of April are popular and, with some reservations, November as well. Our editorial team recommends May and June as well as September and October as the absolute best travel months.
