About pollen in Corona
Grass pollen is the only category active in Corona today, and levels are quite low. Most people, even those with sensitivities, should notice little to no effect from grass pollen right now. Overall, this is a quiet day for outdoor allergens across the board. Looking ahead, the next several days are expected to hold steady at these same low grass pollen levels, so no significant changes are on the horizon. This lull fits the season, as the region's typical spring bloom from trees like oak, sycamore, and eucalyptus has already wound down, and grass pollen itself is past its peak from late spring. With ragweed season still a ways off in late summer, this stretch of midsummer is generally one of the calmer periods for allergy sufferers in the area.
