Why Allergies Are Worse in Louisville
Louisville's Ohio River Valley basin geography creates one of the most challenging allergy environments in the eastern United States, with inversions trapping pollen and humidity fueling year-round mold.
Ohio River Valley Bowl
Louisville sits in a basin where valley topography and frequent temperature inversions prevent pollen, mold, and pollutants from dispersing, creating concentrated allergen exposure.
Urban Heat Island Effect
Louisville's urban heat island extends the growing season for ragweed and grass, while amplifying ground-level ozone that worsens allergic reactions.
Ohio River Humidity
The Ohio River maintains high humidity that sustains outdoor mold counts and keeps pollen grains hydrated near ground level through Louisville's long, hot summers.
