Sugar maple
Acer saccharum
Low today, mostly weed pollen.
Last updated August 14, 2026
Weed pollen is the main contributor to today's mild conditions in Greensboro, though it remains at a low level that most people won't notice. Tree pollen is essentially quiet at this point in the season. Overall, it's a comfortable day for spending time outdoors, with only those especially sensitive to weed pollen likely to feel any effect. Looking ahead, this pattern should hold steady through the next several days, with weed pollen staying low and tree pollen continuing to register as very low. This lull fits the season well: trees like birch, cryptomeria, and cunninghamia had their peak release back in spring, and grass pollen from late spring has also tapered off. As late summer moves along, keep in mind that ragweed and other weeds tend to become more active in the coming weeks, so it's worth watching for a gradual uptick as fall approaches.
