Platanus acerifolia
Low today, mostly weed pollen.
Last updated August 15, 2026
Weed pollen is the main presence in the Bronx today, though at a low level that most people will barely notice. Tree pollen is essentially quiet at this point in the season, with only trace amounts in the air. Overall, conditions are mild and should pose little trouble for the average allergy sufferer, though those especially sensitive to weed pollen may feel a slight effect outdoors. Looking ahead, this pattern is expected to hold steady over the next several days, with weed pollen staying at a low level and tree pollen remaining minimal. This lines up with the typical rhythm of mid-August, when trees such as oak, elm, honeylocust, and Robinia are long past their spring peak and largely dormant, while weeds continue their gradual rise heading toward the more active ragweed season in the weeks ahead. For now, outdoor conditions remain fairly comfortable across the city.
