Gleditsia triacanthos
Very low today, mostly grass pollen.
Last updated July 9, 2026
Pollen levels in Rochester are quiet today. Tree pollen is absent, and grass pollen is registering only at a very low level, so most people should move through the day without any noticeable irritation. Overall, this is about as mild as pollen conditions get. Looking ahead, grass pollen is expected to hold steady at a very low level through the next several days, with no significant change on the horizon. Tree pollen should remain a non-issue as well, which makes sense this time of year since local trees such as linden, honeylocust, plane, pyrus, and zelkova have already finished their spring pollen release. With grass staying subdued and ragweed season still weeks away, allergy sufferers in the area can expect a calm stretch ahead.
