Frequently asked questions about Montana pollen forecasts
Why can Montana pollen vary so much between cities?
Elevation, valley shape, wind exposure, snowmelt timing, river corridors, and local vegetation all matter. Missoula, Billings, Bozeman, and Great Falls can be in different allergy phases even during the same week.
Is sagebrush a real allergy trigger in Montana?
Yes. Sagebrush is different from ragweed, but both can contribute to late-season weed pollen symptoms. Sagebrush, wormwood, kochia, chenopods, and ragweed are most noticeable around dry open land, rangeland, roadsides, and disturbed soil.
Why do windy Montana days feel worse for allergies?
Dry wind can lift pollen, grass fragments, weed pollen, dust, and plant debris across long distances. That can make a day feel harsh even when the measured pollen count is not the highest of the season.
How is Billings different from Missoula or Kalispell?
Billings has more eastern plains, dry wind, grassland, and sagebrush influence. Missoula and Kalispell are more mountain-valley and forest influenced, with different tree timing, moisture, mold potential, and valley-trapping patterns.
