San Francisco was established in 1776 Â by the Spanish with a fort at the Golden Gate and setup a mission for Francis of Assisi on the site. Â In 1848 the Gold Rush swept through California and grew the cities population from 1,000 to 25,000 in just one year turning it into the largest city on the west coast. Â 3/4 of San Francisco was destroyed in the great quake in 1906.
During World War 2 it was the embarkation port for US service members shipping out to fight theÂ JapaneseÂ in the Pacific. Â But due to massive immigration and returning service men the area turned into a centre of liberalism and activism that lead to the Summer of Love and the gay rights movement.
The weather of San Francisco is more chracteristic of a coolish Mediterranean summer climate as the weather is strongly influenced by the cool currents of the Pacific ocean. Â Surrounded on 3 sides by water the bay area has moderate temperature swings and a mild year-round climate with little seasonal temperature variations.
San Francisco does feature a number of distinct micro-climates due to its maritime influences and sharp topography. Â San Francisco is sunny with an average of 260 clear days a year and the rainy period runs from November to April.
