Why Allergies Are Worse in Chicago
Chicago's urban heat island, Lake Michigan humidity, and proximity to the cornbelt ragweed reservoir create overlapping pollen and mold seasons from March through October with no true relief month.
Chicago Urban Heat Island
The urban heat island advances tree-pollen onset by one to two weeks, extends the fall ragweed season into October, and sealed high-rises concentrate indoor dust mites year-round.
Lake Michigan Lakefront Effect
Lake breezes pull pollen inland from suburban sources and drive summer humidity that sustains mold growth after thunderstorms across the metro.
Cornbelt Ragweed Proximity
Prevailing southwest winds carry ragweed pollen from the surrounding agricultural belt into the metro, contributing to Chicago's elevated late-summer counts.
