Willow oak
Quercus phellos
Low today, mostly grass pollen.
Last updated July 1, 2026
Pollen levels across Arlington are modest today, with both tree and grass each registering Low on the index and the overall reading sitting at Low as well. Grass is the type to watch heading into early summer, and the five-day forecast holds it steady at Low throughout, so no notable swings are expected. Tree pollen is also Low for now, with no forecast data available to signal a change, which fits the seasonal pattern as the spring peak from oak, maple, hackberry (Celtis), birch, and sweetgum (Liquidambar) winds down. This time of year typically favors grass over trees, and the current numbers reflect that transition. Weed pollen is not being tracked here, so ragweed season remains a later-summer concern rather than a factor today.
