Moderate Pollen in Corona, CA

About pollen in Corona

Weed pollen is the main contributor to today's moderate overall conditions in Corona, and those sensitive to it may notice some effect through the day. Grass pollen is present but at a very low level, while tree pollen is absent, so any discomfort is far more likely tied to weeds than anything else in the air right now. Looking ahead, this pattern should hold steady over the next several days, with weed pollen remaining the one to watch and grass staying minimal in the background. This lines up with the season: early fall is typically peak time for weeds like ragweed in Southern California, while tree pollen from local species such as oak and eucalyptus stays quiet until it picks up again in spring.
