what is the climate like in san francisco
San Francisco San Francisco has a warm-summer Mediterranean climate (Köppen Csb) characteristic of California's coast, with moist mild winters and dry summers.[91] San Francisco's weather is strongly influenced by the cool currents of the Pacific Ocean on the west side of the city, and the water of San Francisco Bay to the north and east. This moderates temperature swings and produces a remarkably mild year-round climate with little seasonal temperature variation.
