Weather changes in San Francisco

San Francisco is located in the middle latitude, on the west coast of North America. It is surrounded by icy oceans (Pacific Ocean and San Francisco Bay) on three sides. The nearby ocean surface is affected by the California warm current, and the low-temperature seawater in the depths of the ocean rises to the surface. Due to the Pacific high pressure and southwest monsoon, the surface temperature of seawater is extremely low.

In summer, San Francisco is shrouded in icy sea fog, with an average temperature of 15-2 1 celsius and a low temperature of 10- 12 celsius. The temperature in winter is mild, with high temperature 12- 15 and low temperature 7- 10. Spring and autumn is an excessive season, and the hottest weather often appears at this time.
