Last updated July 21, 2026
Pollen levels in Washington Heights are quiet today, with tree pollen essentially absent and nothing of note in the air. For most residents, including those with sensitivities, this should be an easy day with little to no irritation from pollen. Looking ahead, conditions are expected to stay calm over the next several days, with tree pollen remaining at negligible levels. This tracks with the season: the trees common to the area, including oak, elm, linden, honeylocust, and Gymnocladus, released their pollen earlier in the year and are now past their active period. Grass pollen can still linger into midsummer for some sensitive individuals, but overall this is a low-pollen stretch before ragweed and other late-summer allergens become relevant closer to fall.
