Missouri Pollen by City

Missouri's cities read the warm, humid subtropical Southeast pollen calendar: tree pollen peaks Feb–Apr, grass Apr–Sep, and ragweed Aug–Nov — an unusually long, overlapping season — the warm climate stretches grass across much of the year and pushes ragweed deep into autumn. Every city below has its own page with today’s verdict and the full 12-month season calendar.
