Acer rubrum
Low today, mostly weed pollen.
Last updated August 15, 2026
Weed pollen is the main contributor to today's count in Alexandria, though it remains at a low level overall. Tree pollen is barely present, so those with sensitivities should notice little from that source. Altogether, conditions are mild and most people should be able to go about outdoor activities without much irritation. Looking ahead, this pattern is expected to hold steady over the next several days, with tree pollen staying negligible and weed pollen hovering in the low range, ticking up slightly on a couple of days. This is typical for mid-August, when familiar spring trees like oak, elm, maple, plane, and tulip poplar (liriodendron) are dormant and the season's attention shifts toward weeds such as ragweed, which tends to build through late summer and into fall. For now, though, sensitive individuals should find this a fairly easy stretch.
