No notable pollen right now.
Last updated November 14, 2026
Pollen is essentially quiet across Flatbush today. Tree pollen is sitting at none, and there is no indication of any other type stirring either. For most residents, this means outdoor activities should pose little to no risk of pollen-related irritation. Looking ahead, conditions are expected to remain calm, with tree pollen staying flat over the next stretch of days. This lines up with the season, as mid-November falls well outside the active growth period for local trees like oak, elm, honeylocust, and pear, which typically release their pollen in spring. Grass and ragweed season has also wound down for the year, so allergy sufferers can expect a steady, low-pollen stretch heading into the colder months.
