San Francisco’s weather, as shown in the live forecast above, is defined by its Pacific coast location. The city sees mild, foggy summers and cool, wet winters, with the famous Karl the Fog often rolling in from the ocean during the warmer months.
What is the typical weather pattern in San Francisco?
San Francisco has a Mediterranean climate with dry summers and wet winters. Fog is a defining feature, especially in July and August, when it can linger all day. Temperatures rarely exceed 25°C or drop below 5°C, thanks to the moderating influence of the Pacific. The rainy season runs from November to March, with most of the city’s 600mm of annual rainfall falling then.
