Low Pollen in Santa Rosa, CA

About pollen in Santa Rosa

Grass pollen is the main player in Santa Rosa today, sitting at a Low level and edging out tree pollen, which has dropped to Very Low. The overall index reads Low at a 2, so airborne pollen is present but modest. The five-day forecast holds grass steady at Low throughout, suggesting little change in the days ahead. This tracks with the season: tree species like Oak, Celtis, Sequoia, Salix, and Pine have largely finished their spring push, while grasses tend to stay active into early summer. Weed pollen isn't reflected in today's data, which fits the calendar since ragweed typically waits until later in the year.
