Last updated July 28, 2026
Pollen levels in Corona are quiet today, with tree pollen essentially absent and no significant activity from any other source. Those who typically react to airborne allergens should find today an easy one, with little to no irritation expected outdoors. Looking ahead, tree pollen is expected to remain minimal over the next several days, offering continued relief for anyone sensitive to species like oak, honeylocust, willow, and cherry that populate the area. This lull fits the season, as local trees finished releasing their pollen months ago; the greater concern this time of year tends to be grasses and, later, ragweed as summer progresses into fall.
