Reno Pollen Report
Reno's high-desert setting in the Truckee Meadows means wind, and wind means pollen travels. Juniper and elm start the season in early spring, grasses and cottonwoods along the Truckee River carry the summer, and sagebrush and rabbitbrush — the desert's signature shrubs — dominate the fall. The dry air keeps pollen airborne for long distances.

What drives allergies in Reno
Trees: juniper, elm, and cottonwood (March – June)
Western juniper covers the hills around Reno and is the metro's signature spring allergen; Siberian elm and cottonwoods along the Truckee contribute.
Grasses: May – July
Native grasses and irrigated lawns pollinate in early summer across the valley.
Weeds: sagebrush and ragweed (August – October)
Big sagebrush (Artemisia tridentata) dominates the surrounding desert; ragweed and Russian thistle add to windy fall days.
Mold: low, with river and irrigation exceptions
The desert climate keeps outdoor mold modest, with rises along the Truckee corridor and in irrigated landscapes.

Frequently asked questions
What is the pollen count in Reno today?
PollyMap publishes real, microscope-verified pollen counts for Reno — measured from physical air samples. The latest report on this page shows current tree, grass, weed, and mold levels.
Is the pollen count high in Reno right now?
Reno's worst stretches are April–May (juniper, elm), June (grasses), and September (sagebrush). The measured reports on this page show today's actual levels.
When is allergy season in Reno?
March through October: trees in spring, grasses in early summer, and sagebrush in the fall.
Why do windy days make Reno allergies worse?
The Truckee Meadows sits in a wind corridor between the Sierra and the desert — gusts carry juniper and sagebrush pollen long distances and keep it aloft all day.
Is pollen still bad in Reno in the fall?
Reno's fall weed season — ragweed, sagebrush, and Russian thistle — runs through about late October. Reno cools faster than southern Nevada, so November usually brings real relief until spring.
