Low today, mostly weed pollen.
Last updated August 15, 2026
Weed pollen is the most active type in East Harlem today, though levels remain on the low side and should be no more than a mild nuisance for most people. Tree pollen is essentially quiet at this point, so anyone sensitive to trees like oak, honeylocust, or Zelkova should notice little to no effect right now. Over the next several days, this pattern looks set to continue: tree pollen will stay very low, while weed pollen holds steady in the low range with only slight day-to-day fluctuation. This fits the seasonal calendar, since late summer typically marks the start of ragweed and other weed pollen season, while trees such as oak, pyrus, and Styphnolobium have long since finished their spring release. Overall, conditions should remain manageable for most residents through the week.
