Last updated November 14, 2026
Pollen levels in Richmond Hill are quiet today, with tree pollen sitting at essentially none. Anyone sensitive to airborne allergens should find little to no irritation outdoors right now, making it a comfortable day for spending time outside. Looking ahead, conditions are expected to remain calm over the next several days, with tree pollen staying at the low end. This lull fits the season well: by mid-November, trees such as plane, maple, pyrus, linden, and oak have long since finished releasing pollen, and the next active period for these species will not begin until growth resumes in spring. For now, allergy sufferers in the area can expect a quiet stretch with little pollen-related discomfort.
