Connecticut Pollen by City

Connecticut's cities read the cold-temperate Northeast pollen calendar: tree pollen peaks Mar–May, grass May–Jul, and ragweed Aug–Oct — a sharply defined calendar — a hard winter lull, then a compact spring tree burst before grass and a long ragweed fall. Every city below has its own page with today’s verdict and the full 12-month season calendar.
