Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in East Flatbush today, sitting at a Low level (2) and edging out tree pollen, which has dropped to Very Low (1). The overall index reads Low (2), so conditions are fairly mild across the board right now. Grass is expected to hold steady at Low through the five-day forecast, with no notable rise or fall on the horizon. That pattern fits the late-spring-into-early-summer window, when grass typically takes over as the dominant source while tree pollen winds down. The local plane, maple, ash, zelkova, and oak that lead the spring season are well past their peak and contributing little at this point. Weed pollen, including ragweed, isn't reporting yet and generally stays quiet until later in the summer.
