Low today, mostly weed pollen.
Last updated August 15, 2026
Pollen levels across Manhattan are running low today. Weed pollen is the more active of the two categories present, though it remains in a mild range that most people won't notice much. Tree pollen is barely registering at this point in the season, so any lingering sensitivity to species like plane, elm, oak, ginkgo, or pyrus should be minimal for now. Looking ahead, this pattern is expected to hold steady over the next several days, with tree pollen staying negligible and weed pollen fluctuating gently between low and slightly noticeable levels. This is typical for mid-August, a period that sits between the spring tree pollen season and the more prominent ragweed activity that tends to build later in the fall. For now, outdoor conditions should remain fairly comfortable for those with seasonal sensitivities.
