No notable pollen right now.
Last updated November 14, 2026
Pollen activity in Rochester is quiet today, with tree pollen sitting at essentially none. Anyone who typically reacts to pollen should find little to notice outdoors right now, as the air is largely clear of it. Looking ahead, tree pollen is expected to remain absent over the next several days, which fits the season. By mid-November, trees such as honeylocust, plane, pyrus, zelkova, and oak have long finished releasing pollen for the year, and the cold has settled in enough to keep them dormant. This lull is typical for late fall, and conditions should stay calm until growth resumes in spring.
