Low today, mostly weed pollen.
Last updated August 14, 2026
Weed pollen is the main contributor to the air today, though it remains at a low level overall. Tree pollen is barely present at this point in the season, so most people should notice little to nothing from that source. For anyone particularly sensitive to weeds, there may be mild awareness of symptoms, but conditions overall are calm and manageable for most of the city. Looking ahead, this pattern should hold steady over the next several days, with tree pollen staying very low and weed pollen fluctuating slightly between low and quiet. This is typical for mid-August, a seasonal lull between the earlier flowering of trees like honeylocust, Callery pear, zelkova, and ginkgo in spring and the ragweed surge that tends to build later in the season. For now, allergy-prone New Yorkers can expect a relatively easy stretch before weed pollen, particularly ragweed, becomes more prominent in the weeks ahead.
