Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main source of activity in Brooklyn today, though it remains at a low level overall. Tree pollen is essentially absent right now, so most people should notice little to nothing in the way of symptoms. Those who are particularly sensitive to grass might feel a mild effect, but for the general population, today counts as an easy day for outdoor activity. Looking ahead, grass pollen is expected to hold steady at this low level over the next several days before easing slightly toward the end of the stretch. Tree pollen should stay quiet, which fits the season, since local trees like linden, honeylocust, and maple typically finish their pollen release earlier in the year. This time of year is really grass season, with tree pollen behind us and ragweed and other late-summer weeds still a ways off.
