Very low today, mostly tree pollen.
Last updated July 28, 2026
Pollen levels in Richmond Hill are quiet today, with tree pollen sitting at a very low level. Most people should be able to go about their day without much irritation, even those who are typically sensitive to pollen in the air. Looking ahead, tree pollen is expected to stay at this same low level over the next few days, offering little cause for concern. This lull fits the season well, since trees like oak, maple, plane, honeylocust, and birch release most of their pollen in spring, long before midsummer. With that cycle behind us, attention will gradually shift toward grasses now and ragweed later in the season as late summer and fall approach.
