Why Allergies Are Worse in Delaware
Delaware's compact geography bridges the Piedmont and Coastal Plain, with Delaware Bay humidity driving year-round mold and a spring pollen season that starts earlier than New England neighbors.
Delaware Bay Humidity Corridor
Persistent maritime humidity from the Delaware Bay and Atlantic keeps mold spore counts elevated nearly year-round, especially Alternaria and Cladosporium that thrive on damp leaf litter.
Loblolly Pine Yellow Pollen Plume
Southern Delaware's loblolly pine stands release massive yellow pollen clouds in April through May that coat surfaces statewide, compounding oak and birch tree pollen peaks.
Salt Marsh and Tidal Wetland Mold
Extensive tidal salt marshes along the Inland Bays and Bombay Hook generate decaying organic matter that feeds airborne mold spore loads, particularly after summer storms.
