About pollen in Garden Grove

Grass pollen is the main player in Garden Grove today, sitting at a Low level (index 2) and edging out tree pollen, which has dropped to Very Low (index 1). The five-day grass forecast holds steady at the same Low reading, so expect little change in the days ahead. This tracks with the season, as grass typically drives the count through late spring and early summer while tree pollen winds down. Local allergenic trees like Pine, Plane, Archontophoenix, Cupaniopsis, and Celtis are contributing only modestly at this point. Overall conditions remain Low.
