Red maple
Acer rubrum
Very low today, mostly grass pollen.
Last updated July 9, 2026
Pollen levels in Washington, DC are quiet today. Grass is the only type registering any activity, and even that is very low, so most people should be able to go about their day without much irritation. Tree pollen is absent entirely, giving a break to anyone typically sensitive to species like Zelkova, Linden, or Elm. Looking ahead, conditions are expected to hold steady over the next several days, with grass staying at a similarly low level and tree pollen remaining out of the picture. This lines up with the seasonal pattern: local trees such as Liquidambar and Celtis have already finished their main spring release, and grass season, while technically still active, is winding down heading into midsummer. With ragweed season still weeks away, this is shaping up to be a comfortable stretch for allergy sufferers in the area.
