About pollen in Corona

Conditions in Corona are calm for pollen right now, with nothing particularly aggressive circulating in the air. Late July tends to fall in a quieter stretch between the grass pollen that dominates late spring and early summer and the weed pollen that typically ramps up as late summer moves toward fall, so most people should find today comfortable if they spend time outdoors. Looking ahead, expect conditions to stay relatively mild over the next few days, though warm, dry weather can still stir up occasional grass pollen from lawns and open fields around the area. Local trees such as olive, sycamore, and eucalyptus finished their heavier pollen release back in spring, so tree pollen is not a major factor this time of year. As summer progresses, keep an eye out for weeds like ragweed and sagebrush, which tend to become more active as the season shifts toward early fall.
