Low Pollen in Berkeley, CA

About pollen in Berkeley

Grass pollen is the main player in Berkeley today, sitting at a Low level (2) and accounting for the overall Low reading of 2 across the area. Tree pollen has dropped to None, so the usual local contributors like Ash, Liquidambar, Tristaniopsis, Pittosporum, and Prunus aren't adding much to the air right now. The forecast keeps grass steady at the same Low level for the next several days before easing slightly toward the end of the window. This fits the season, as grass typically holds its ground through late spring and early summer while spring tree pollen winds down. Weed pollen, including ragweed that tends to arrive later in summer and fall, has no data available at this time.
