Why Allergies Are Worse in Maryland
Maryland's Chesapeake Bay corridor, DC-suburban hardwood canopy, and Eastern Shore wetlands create a uniquely humid allergy environment where tree pollen, ragweed, and mold overlap for eight months.
Chesapeake Bay Humidity Corridor
The Bay's evaporative moisture blankets central Maryland in summer dew points often above 70°F, sustaining high mold spore counts and rupturing pollen grains into smaller, lung-penetrating fragments.
DC/Baltimore Suburban Oak-Sycamore Canopy
Dense oak, sycamore, and sweetgum street trees through Montgomery, Prince George's, and Baltimore counties generate intense April–May tree pollen, amplified by Baltimore's urban ozone.
Eastern Shore Mold Reservoir
Flat, poorly drained Coastal Plain farmland and tidal marshes on the Delmarva Eastern Shore create persistent ground-level mold and ragweed conditions reaching peak in late summer.
