Why Allergies Are Worse in Los Angeles
Los Angeles's geography — a coastal basin surrounded by mountains — traps both smog and allergens at ground level. The combination of warm temperatures, ocean humidity, and temperature inversions creates some of the worst allergy conditions in the country.
Santa Ana Winds
Hot, dry winds from the desert redistribute pollen and dust across the LA basin, triggering allergy flare-ups far from the pollen source.
Temperature Inversions
A warm air layer traps allergens and smog near ground level, especially during summer months, concentrating exposure in populated areas.
Year-Round Warmth
LA's mild climate supports pollen production in every month. There is no winter freeze to stop allergen exposure.
