Norway maple
Acer platanoides
Moderate today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Newton today, sitting at a moderate level while overall pollen also registers as moderate. Tree pollen has eased to low, which fits the late-June timing—the spring surge from local species like Maple, Oak, Ash, Honeylocust, and Zelkova is well past its peak. Looking ahead, grass should hold steady at moderate for the next few days before dipping slightly toward the end of the forecast window, and tree pollen is expected to stay low throughout. This grass-dominant pattern is typical for early summer in the region. Weed pollen data isn't available right now, though ragweed generally doesn't become a factor until late summer.
