Very low today, mostly tree pollen.
Last updated August 15, 2026
Pollen levels in Flatbush are quiet today, with both tree and weed sources sitting at very low levels. Neither is likely to cause much trouble, even for those who tend to react strongly this time of year. It should be an easy day to spend time outdoors without much concern about pollen exposure. Looking ahead, conditions are expected to stay calm through the next several days, with tree pollen holding steady at very low levels and weed pollen edging up just slightly midweek before settling back down. This lull fits the season — the trees around the neighborhood, including honeylocust, oak, elm, and pear, finished their heavier pollen release back in spring, while weeds like ragweed typically don't pick up until later in the summer and into fall. For now, allergy-prone residents can expect a relatively easy stretch.
