Very Low Pollen in Orange, CA

About pollen in Orange

Pollen levels in Orange are quiet today. Grass is the only type registering any activity, and even that is at a very low level, so most people should be able to go about their outdoor plans without much concern. Tree pollen is absent entirely, meaning trees like Lophostemon, Washingtonia, Olea, Cinnamomum, and Jacaranda are not contributing to the count right now. Looking ahead, this calm pattern is expected to hold steady over the next several days, with grass staying at a similarly low, barely noticeable level and tree pollen remaining absent. This lull fits the season well: local trees typically finish their pollen release in spring, and by midsummer grass pollen is often past its most active stretch, tapering into the lighter background levels we're seeing now. Weed pollen, including ragweed, tends to pick up later in the summer and into fall, so conditions should stay comfortable for the near term.
