Understanding San Francisco's Microclimates

San Francisco is famous for its diverse microclimates. These localized weather patterns result from the city's unique topography and proximity to the Pacific Ocean. Factors like hills, valleys, and the presence of fog all play a significant role. In our experience, understanding these microclimates is key to navigating the city's weather effectively.

Key Factors Influencing Microclimates

Several key factors contribute to San Francisco's microclimates:

• Hills and Valleys: Hills block wind and create sheltered areas, while valleys can trap fog and moisture.

Notable Microclimates

Some of San Francisco's most well-known microclimates include:

• The Sunset District: Known for its fog and cool temperatures, even in summer.
