Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver across the Upper West Side today, sitting at a moderate level (3) and accounting for the overall moderate reading. Tree pollen has dropped off entirely to none, so the local allergenic trees like Linden, Oak, Honeylocust, Pyrus, and Elm are not contributing right now. The forecast holds grass at moderate for the next couple of days before easing to a lower level through the rest of the period. This fits the season, as grass pollen typically peaks in late spring and early summer while the spring tree surge has passed. Weed pollen remains unmeasured for now, though its prominence usually arrives later toward the end of summer.
