Platanus acerifolia
Moderate today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in the Bronx today, sitting at a moderate level and pushing the overall index to moderate as well. Tree pollen has dropped to very low, so local species like oak, honeylocust, Styphnolobium, Zelkova, and maple are contributing little at this point in the season. That's typical for late June, when the spring tree peak has faded and grass takes over through early summer. The forecast holds grass steady at moderate for the next several days before a brief dip and a return to moderate, so expect little change overall. Ragweed and other weeds aren't a factor yet, as that season arrives later in summer and into fall.
