No notable pollen right now.
Last updated November 14, 2026
Pollen is essentially a non-issue in Washington Heights today. Tree pollen is reading at none, and with no grass or weed activity reported either, anyone prone to seasonal allergies should find the air comfortable to breathe this morning. Looking ahead, conditions are expected to stay quiet, with tree pollen holding at none through the available forecast. This lines up with the season: mid-November falls well after the fall pollen window has wound down, and local trees like oak, elm, linden, honeylocust, and Gymnocladus are dormant now, with their next active stretch not arriving until spring. For the time being, there is little reason to expect pollen to factor into how you feel outdoors.
