Low today, mostly weed pollen.
Last updated August 14, 2026
Weed pollen is the main presence on the Upper West Side today, though it remains at a low level that most people won't notice much. Tree pollen is essentially quiet at this point in the season, so overall conditions are mild and should pose little trouble for the average person, with only those especially sensitive to weed pollen likely to feel any effect. Looking ahead, this pattern should hold steady over the next several days, with weed pollen staying low to moderate and tree pollen continuing to register at a very low level throughout. This lines up with the usual seasonal rhythm — trees like oak, linden, honeylocust, pyrus, and elm release their pollen mainly in spring and are largely dormant by mid-August, while weeds are just beginning their more active stretch, which typically builds into early fall.
