Tilia cordata
Very low today, mostly weed pollen.
Last updated September 29, 2026
Pollen levels in Amherst are quiet today. Tree pollen is absent entirely, and weed pollen is only barely present, registering at a very low level. Overall, this adds up to one of the calmer stretches of the season, with little reason for most people to notice any effects, even those who are typically sensitive. Looking ahead, tree pollen should stay out of the picture over the next several days, which fits the time of year, since species like maple, hornbeam, lilac, and honeylocust finished releasing pollen back in spring. Weed pollen, on the other hand, is expected to inch up slightly and hold at a mild but steady level through the rest of the week. This lines up with the usual late-season pattern, as ragweed and related weeds tend to linger into early fall before tapering off with the first sustained cold snaps.
