Low Pollen in Sunnyvale, CA

About pollen in Sunnyvale

Grass pollen is the main player in Sunnyvale today, sitting at a Low level (2) and edging out tree pollen, which has dropped to Very Low (1). The overall index lands at Low (2), so conditions are fairly mild across the board. The five-day grass forecast holds steady at Low (2) throughout, suggesting little change in the days ahead. This tracks with the season, as grass tends to be the dominant source through late spring and early summer, while the local allergenic trees—Pistacia, Plane, Maple, Ash, and Liquidambar—have largely moved past their springtime peak. No weed data is available at this time.
