Sugar maple
Acer saccharum
Low today, mostly grass pollen.
Last updated July 9, 2026
Pollen activity around Greensboro remains quiet today. Both tree and grass pollen are running very low, so most people should notice little to no irritation outdoors. It's a comfortable day for spending time outside, even for those who are usually sensitive to seasonal pollen. Looking ahead, conditions are expected to stay mild through the next several days, with grass pollen ticking up slightly to a low-moderate level midweek before easing back down. Tree pollen from local varieties like oak, pine, maple, ash, and hickory has largely wound down for the season, which is typical for midsummer in the region. Grass remains the main source of pollen this time of year, though current levels suggest only minor, if any, impact for most residents.
