GENERAL INFORMATION ABOUT SAN FRANCISCO

San Francisco is a major city in California, the centerpiece of the Bay Area, well-known for its liberal community, hilly terrain, Victorian architecture, scenic beauty, summer fog, and great ethnic and cultural diversity. These are only a few of the aspects of the city that make San Francisco one of the most visited cities in the world.

Although huge in terms of offerings, San Francisco is physically quite compact. It is located on a seven-by-seven mile (11 x 11km) square of land at the tip of a peninsula between the San Francisco Bay and the Pacific coast. It has a population of 812,000 which represents a small fraction of the entire Bay Area population of 7.1 million. San Francisco is just one of the cities which makes up the entire San Francisco Bay Area. San Francisco’s neighbors -Oakland and Berkeley east of the Bay Bridge, Marin County north of the Golden Gate Bridge, and the Peninsula south of the city are all part of separate counties, each with their own governments and local public transportation systems. San Francisco suffers from crime in some downtown districts like the Tenderloin, Mid Market, 6th Street, Soma and the Western Addition. The south-eastern part of the city also suffers from violent crime. Visitors should be aware of their surroundings when walking late at night near some downtown hotels. San Francisco also has a high rate of pedestrian and bicycle fatalities.

Climate

San Francisco has a mild climate, with cool, wet winters and dry summers. In most months, you can expect the high temperature to be in the upper 50s, 60s or low 70s degree Fahrenheit (15-25°C). However, these mild temperature readings belie a unique climate not shared by other major cities in the state or country. Essentially San Francisco is never warmer than 73 degrees but never colder than 50 degrees. The nights are chilly so usually people in San Francisco always carry around a light jacket because the temperatures can

drop or rise drastically within an hour.

Summer days usually start out under fog, slowly burning off towards the ocean into a sunny albeit windy afternoon. Measurable precipitation during the summer months is rare, although light drizzle is possible. Humidity is very constant, but rarely uncomfortable. At late afternoon, when the fog and wind returns people generally find themselves needing a jacket (and this is summer!). There are some days when the fog lingers all day.

In the winter, the rainy season is in full swing. That being said, the chances for a calm, windless, sunny day are actually higher in the winter than in the summer! However, the overall temperatures are going to be lower in the winter.

Spring and fall are not so much seasons in themselves in San Francisco, but rather they are quick transitional periods with some days resembling summer and others the winter. Fall in particular is a good time to visit because the summer wind & fog has mostly gone, but the rainy season has not yet started. The late summer month of September, as summer transitions into fall, is the warmest and driest month of the entire year for San Francisco. Heat waves can occasionally occur around this time of year.

Within these general rules, San Francisco also has a series of microclimates created by the city’s topography and maritime setting. Large hills in the city’s center block much of the fog, wind, and precipitation that rolls in from the Pacific Ocean. Because of this, there can be significant weather differences in different parts of the city and the surrounding Bay Area at the same time. Generally, the more windward areas along the coast are cooler and foggier, while the more leeward areas in the east are warmer and drier. Temperature differences of 10-15 degrees or so are common on days where the fog persists on the western side of the city. These differences continues as you move east, out of the city and into the outer East Bay (on the other side of the hills from Berkeley and Oakland), where it can be much hotter and drier. Local meteorologists routinely have three forecasts: one for the coast, one for the bay, and one for the inland areas. In short, if you don’t like the weather, perhaps travel a few miles east or west to your desired climate.
