Montana Pollen by City
Montana's cities read the high-elevation Mountain West pollen calendar: tree pollen peaks Mar–May, grass May–Jul, and ragweed Aug–Oct — short, sharp seasons set late by elevation, with sagebrush adding to the late-summer weed load. Every city below has its own page with today’s verdict and the full 12-month season calendar.
