Pollen in San Diego, CA

About pollen in San Diego

Pollen levels across San Diego are quiet today, with tree pollen essentially absent. Anyone who typically reacts to trees like jacaranda, magnolia, podocarpus, or syagrus should find little to contend with, and overall conditions make for an easy day for allergy sufferers. Looking ahead, this calm pattern is expected to hold over the next several days, with tree pollen staying at negligible levels. This tracks with the season, since most local trees, including cupaniopsis and the others common to the area, are well past their active pollination period and won't ramp up again until spring. For now, there's little reason to expect trees to cause noticeable symptoms.
