San Francisco offers some of the city’s most breathtaking views, with Golden Gate and Bay Bridges, Alcatraz and Treasure Islands and the steep hills that offer breathtaking views everywhere.

The weather in San Francisco during the year

The weather in San Francisco is relatively stable throughout the year, with no major temperature fluctuations between the summer and winter seasons. The most important factors influencing the weather are winter rain and summer fog.

The average rainfall in San Francisco can be misleading because different years show very different patterns in the El Niño cycle with very wet winters, while other years have almost no rain. Even in wet years, rain tends to fall in large quantities over several days and not continuously from December to February.

Summer fog is an important factor in San Francisco, as it is located on most of the American Pacific coast. This usually happens in June, but often spreads in May and July. Fog can be dense in the bay and can cause the temperature to become much cooler. The high humidity and wet fog make early summer a bad time to visit San Francisco.
