Low today, mostly weed pollen.
Last updated September 30, 2026
Weed pollen is the only real presence in Manhattan's air today, and it remains at a low level. Tree pollen is absent entirely, so anyone sensitive to oak, plane, or elm can breathe easy on that front. Overall, this is a mild day for allergies, with weed pollen being the sole factor worth noting, and even that should stay mostly in the background for most people. Over the next several days, weed pollen is expected to hold steady in the low range, dipping slightly at times but not rising much beyond where it sits now. Tree pollen should remain absent throughout the period, which is typical for this point in the year since species like oak, elm, and honeylocust release their pollen in spring, not fall. Instead, early autumn belongs to weeds, particularly ragweed, so those with sensitivities may notice mild symptoms on any given day, though nothing suggests a sharp increase is coming.
