Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Manhattan today, sitting at a moderate level (3) and pushing the overall index to moderate as well. Tree pollen has dropped off to none, which fits the calendar now that the spring surge from Oak, Plane, Elm, Styphnolobium, and Honeylocust has passed. The forecast holds grass steady at moderate for the next couple of days before easing to a lower level (2) through the end of the period. This pattern is typical for late spring and early summer, when grass tends to dominate after the trees wind down. Weed pollen isn't reported in the current data, though that category generally builds later in the season.
