Why Allergies Are Worse in Baltimore
Baltimore's position on the Chesapeake Bay with its urban heat island and industrial corridors creates one of the Mid-Atlantic's most challenging allergy environments.
Chesapeake Bay Harbor Humidity
Persistent Bay moisture keeps dew points above 70°F in summer, sustaining outdoor mold spore counts and rupturing pollen grains into smaller allergenic fragments.
Patapsco Industrial Corridor
Vacant lots and disturbed industrial land along the Patapsco River provide ideal ragweed habitat, with urban ozone amplifying pollen-related airway inflammation.
Urban Heat Island Effect
Baltimore's dense urban core advances tree pollen onset and extends the ragweed season compared to surrounding suburbs and rural areas.
