Norway maple
Acer platanoides
Low today, mostly tree pollen.
Last updated July 28, 2026
Tree pollen is the only type registering in Newton today, and it remains on the low side. Most people should get through the day without much irritation, though those especially sensitive to tree pollen from maple, oak, honeylocust, zelkova, or ash may notice a mild effect. Looking ahead, tree pollen is expected to ease slightly and stay low over the next several days. This tracks with the season, since the heavier tree pollen releases of spring are well behind us, and the counts we are seeing now reflect the quieter summer lull before ragweed and other late-season pollens typically pick up in the fall.
