Why Allergies Are Worse in Seattle
Seattle's Puget Sound marine climate creates a unique allergy environment where persistent moisture drives year-round mold alongside intense tree and grass pollen seasons.
Marine Moisture and Year-Round Mold
Puget Sound humidity and persistent cloud cover keep outdoor and indoor mold spore counts elevated throughout the year, with Cladosporium and Alternaria peaking July through November.
Urban Creek Alder Corridors
Red alder lining Seattle's urban creeks and greenbelts produces the city's heaviest tree pollen from February through April, with counts often exceeding very-high thresholds at the NAB station.
Summer Wildfire Smoke
Smoke from Cascade and eastern Washington fires routinely pushes Seattle into unhealthy AQI ranges July through September, compounding asthma and allergic rhinitis symptoms during grass pollen peak.
