Norway maple
Acer platanoides
Low today, mostly tree pollen.
Last updated August 14, 2026
Pollen levels in Newton are low today, with tree and weed pollen both sitting at the milder end of the scale. Most people should be able to get through the day without much irritation, though those who are particularly sensitive might notice a mild effect. Grass pollen is not registering as a factor right now. Looking ahead, conditions are expected to stay mild through the coming days, with both tree and weed pollen edging down slightly by midweek. This is typical for mid-August, a quieter stretch between the spring tree season—when species like oak, maple, and zelkova are most active—and the ragweed-driven weed pollen that tends to pick up as autumn approaches. For now, though, the outdoor air remains relatively calm for allergy sufferers.
