Low Pollen in Washington, DC

About pollen in Washington

Grass pollen is the main driver in Washington today, sitting at a moderate level (3) and pushing the overall index to moderate as well. Tree pollen has dropped to none, so the city's allergenic trees—Linden, Zelkova, Liquidambar, Celtis, and Elm—are no longer meaningful contributors at this point in the season. Grass is expected to hold steady at moderate for the next couple of days before easing to a lower level (2) through the rest of the forecast period. That pattern fits late spring and early summer, when grass typically peaks after the spring tree season has wound down. Ragweed and other weeds are not yet a factor here, with no data reported for that category today.
