Top Allergens in Caldwell

Sagebrush Pollen: Dominant in the late summer and early fall, sagebrush releases pollen that can cause sneezing, congestion, and itchy eyes.
Mountain Cedar: Native to the region, mountain cedar pollen peaks in early spring and triggers allergic rhinitis symptoms in many locals.
Timothy Grass: This common grass flourishes in late spring through midsummer, producing pollen that affects sinus health and breathing.
Dust Mites: Although less seasonal, dust mites thrive indoors in Caldwell’s dry climate, contributing to year-round sinus irritation for sensitive individuals.

Allergy Seasonal Calendar

In Caldwell, spring begins with tree pollen such as mountain cedar peaking in March and April. Late spring and early summer bring increased grass pollen from May through July, including timothy grass. Summer transitions into fall with sagebrush pollen dominating from late August to October.
