Pollen in Bellevue, WA

About pollen in Bellevue

Pollen activity in Bellevue tends to be quiet by early October, as the region moves past the peak growing season for most plants. Trees such as alder and birch, which drive the heaviest pollen counts in spring, are dormant this time of year, and grass pollen has largely tapered off after its late spring and summer run. Weed pollen, including ragweed, can still appear in some areas into early fall, but it is typically a smaller factor in the Pacific Northwest than in other parts of the country. Looking ahead, conditions are likely to stay mild for allergy sufferers over the next few days, with any lingering weed pollen gradually fading as temperatures cool and rainfall increases. This seasonal lull is typical for autumn in the area, with the next notable uptick in pollen not expected until alder and other early trees begin releasing pollen in late winter or early spring.
