Norway maple
Acer platanoides
Very low today, mostly weed pollen.
Last updated September 29, 2026
Pollen levels in Newton are quiet today. Tree pollen is absent entirely, and weeds are registering only a very low presence, the kind of level that most people will not notice at all. Overall, this is a low-impact day for allergy sufferers, with little reason to expect symptoms tied to airborne pollen. Looking ahead, the pattern should hold steady through the next several days, with weed pollen staying at a similarly low level and tree pollen remaining absent. This fits the time of year: local trees such as oak, maple, zelkova, koelreuteria, and prunus finished releasing pollen months ago, and their next active period will not arrive until spring. Weeds, including ragweed, are winding down as fall progresses, so the mild presence being reported now is likely to continue fading rather than intensify.
