Why Allergies Are Worse in San Francisco
San Francisco's unique microclimate — defined by fog, ocean influence, and steep topography — creates different allergy conditions than most California cities. Indoor allergens dominate over outdoor pollen.
Persistent Fog
Karl the Fog keeps humidity high year-round, creating perfect conditions for dust mites and mold in SF's older housing stock.
Ocean Breeze
Onshore winds actually reduce outdoor pollen counts in the city, but push humid air inland where it supports allergen growth.
Microclimates
SF has dozens of microclimates. The Mission District can be 15°F warmer than the Sunset, creating very different allergen exposure within a few miles.
