Low today, mostly tree pollen.
Last updated July 20, 2026
Tree pollen is the main contributor to today's count in East Harlem, though it remains at a low level overall. Grass pollen is present as well but at a very low level, so it should go largely unnoticed. For most residents, today should be a comfortable day with little in the way of pollen-related irritation, even for those who tend to be sensitive. Looking ahead, conditions are expected to hold steady over the next stretch, with tree pollen staying low and grass pollen remaining minimal. This is a bit of a quieter stretch for the season — the heavier tree pollen from species like oak, plane, and honeylocust typically peaks earlier in spring, while zelkova and Styphnolobium contribute lighter amounts later in the season. With summer underway, overall pollen activity is fairly subdued right now, though it's worth keeping in mind that ragweed and other late-summer pollens will become more relevant as the season progresses.
