Very Low Pollen in San Diego, CA

About pollen in San Diego

Pollen activity around San Diego remains minimal today. Tree pollen is absent, and weed pollen is registering at only a very low level, meaning most people should notice little to nothing in the way of symptoms. Overall, it is a quiet day for allergy sufferers. Looking ahead, this calm pattern is expected to hold steady, with weed pollen staying low and tree pollen continuing to show no activity. This fits the season, as local trees such as jacaranda, magnolia, and podocarpus are well past their spring pollen peak, and autumn tends to bring only light, intermittent weed pollen rather than a strong surge. For now, conditions look favorable for those who are sensitive to pollen.
