Why Allergies Are Worse in Centennial
Centennial's south Denver suburban landscape features large irrigated residential lots and parks where Kentucky bluegrass dominates, producing heavy grass pollen loads throughout the growing season.
Irrigated Suburban Landscape
Centennial's extensive irrigated lawns, parks, and HOA-maintained common areas sustain Kentucky bluegrass pollen production from May through August, well beyond what the natural semi-arid climate supports.
Semi-Arid Climate
Low humidity and intense sun at 5,700 feet dry out nasal passages, increasing susceptibility to airborne grass and tree pollen.
Front Range Wind Exposure
Westerly winds from the Front Range carry juniper and pine pollen across the south metro area into Centennial, adding tree allergens to the local grass pollen burden.
Urban Heat Island
Centennial's position within the south Denver metro area means slightly elevated temperatures that extend the grass pollen growing season.
