Very low today, mostly tree pollen.
Last updated July 28, 2026
Pollen levels in Sunnyvale are quite low today, with tree pollen the only type registering any activity, and even that is minimal. Most people, including those with sensitivities, should notice little to no irritation from trees such as pistacia, plane, maple, ash, or liquidambar under these conditions. Looking ahead, tree pollen is expected to stay at this same low level over the next several days, offering a stretch of relatively calm air. This lull fits the season well, since local trees typically release their heaviest pollen in spring, meaning late summer tends to bring a natural quiet period before other pollen sources, like weeds, may pick up later in the year.
