No notable pollen right now.
Last updated July 28, 2026
Pollen levels in Washington Heights are quiet today, with tree pollen sitting at essentially none. Anyone sensitive to airborne allergens should find little to react to outdoors right now, making this a comfortable stretch for spending time outside. Looking ahead, conditions are expected to stay calm over the next several days, with only a slight uptick in tree pollen possible by the end of the period. This lines up with the season, since the neighborhood's oaks, elms, lindens, honeylocusts, and Kentucky coffeetrees (Gymnocladus) have largely finished their spring release and won't be a significant source again until next year. For now, grass and weed pollen remain the more likely contributors to any late-summer discomfort as the season progresses.
