Low today, mostly tree pollen.
Last updated August 15, 2026
Weed pollen is the main story in Washington Heights today, sitting at a moderate level that sensitive individuals will likely notice. Tree pollen, by contrast, is nearly absent, so any irritation you're feeling is almost certainly weed-related rather than coming from oaks, elms, or other neighborhood trees. Looking ahead, weed pollen should hold at a similar moderate level through the next couple of days, ease slightly midweek, then tick back up toward the end of the five-day stretch. Tree pollen is expected to stay minimal throughout, which fits the season — trees like oak, linden, and honeylocust finished their heavy pollen release back in spring. Mid-August is prime time for weeds, with ragweed beginning its seasonal climb, so this pattern is typical for this point in the year.
