Why Allergies Are Worse in Denver
Denver's South Platte cottonwood corridors and warm, dry Chinook winds spilling off the Front Range create a pollen funnel across the Mile-High urban basin, extending both tree and grass seasons.
Chinook Winds
Warm downslope Chinook winds accelerate snowmelt and pollen release in late winter, carrying Front Range tree pollen directly into Denver's urban core.
High Altitude Aridity
Denver's semi-arid climate at 5,280 feet means low humidity and intense UV, which dry out nasal passages and make residents more susceptible to airborne allergens.
South Platte Riparian Corridor
The South Platte River and its tributaries support dense cottonwood galleries that funnel pollen through Denver's central neighborhoods.
Urban Heat Island
Denver's expanding metro area raises local temperatures, extending grass pollen seasons and intensifying ragweed production in late summer.
