About pollen in Corona

Pollen activity in Corona is quiet today. With tree, grass, and weed sources all past their active stretches for the year, most residents should find the air fairly calm, and those with sensitivities are unlikely to notice much in the way of symptoms. Over the next few days, conditions should remain similarly subdued. Mid-November falls well outside the usual peak windows for the region — tree pollen from species like oak, sycamore, and olive typically ramps up in late winter into spring, grasses follow in late spring and early summer, and weeds such as ragweed are more of a late-summer and early-fall concern. For now, this is a seasonal lull, and it is a good stretch for allergy sufferers to catch a break before the next active period begins.
