Very low today, mostly weed pollen.
Last updated September 29, 2026
Pollen levels across Brooklyn are quiet today. Tree pollen is absent entirely, and weed pollen is only barely present, registering at a very low level that most people won't notice at all. Overall, this is about as calm as the air gets, so symptoms should be minimal for even those with sensitivities. Looking ahead, tree pollen is expected to stay flat and inactive over the next few days, which fits the season, since local trees like maple, Callery pear, and honeylocust have long finished releasing pollen for the year and won't stir again until spring. Weed pollen, on the other hand, is likely to inch upward slightly, moving from very low to a mild, noticeable level as we move deeper into the fall ragweed season. Anyone who reacts to weed pollen may want to keep an eye on that gradual uptick in the coming days.
