Gleditsia triacanthos
Low today, mostly tree pollen.
Last updated July 28, 2026
Tree pollen is the only type registering in Flatbush today, and it remains at a low level. Most people should get through the day without much trouble, though those with a strong sensitivity to species like oak, elm, or zelkova may notice a mild effect if spending extended time outdoors. Looking ahead, tree pollen is expected to hold steady at this same low level in the near term, offering little change from today. This is consistent with the season, as the heavier tree pollen releases from oak, honeylocust, plane, and elm typically wind down well before midsummer, leaving the air calmer on that front while attention later in the season tends to shift toward grasses and, eventually, ragweed.
