Moderate today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Washington Heights today, sitting at a moderate level and pushing the overall index to moderate as well. Tree pollen has eased to the low range, which fits the late-June timing as the spring contributions from Oak, Honeylocust, Styphnolobium, Zelkova, and Ash continue to fade. Grass is the season's lead source through late spring and early summer, and that holds here right now. The five-day forecast keeps grass steady at moderate, so expect little change in the days ahead. Ragweed and other weeds tend to ramp up later in the summer and fall, but no weed data is available for today.
