South Dakota Pollen by City

South Dakota's cities read the continental Plains pollen calendar: tree pollen peaks Mar–May, grass May–Jul, and ragweed Aug–Nov — the country's worst ragweed — the continental Plains run a long, severe late-summer-into-fall weed season on top of the usual tree and grass peaks. Every city below has its own page with today’s verdict and the full 12-month season calendar.
