Pollen in Washington, DC

About pollen in Washington

Pollen levels in Washington, DC are quiet today, with tree pollen registering essentially none. Anyone who typically reacts to trees like zelkova, linden, elm, or sweetgum should get a break, as conditions are calm across the board right now. Looking ahead, tree pollen is expected to stay flat over the next several days, so no significant changes are anticipated in the near term. This tracks with the season, as the main tree pollen surge of spring has long passed, and the local elms, lindens, and celtis trees have largely finished releasing pollen for the year. Late summer in the DC area tends to bring more attention to weeds, particularly ragweed, as that season approaches in the weeks ahead.
