Low Pollen in Pomona, CA

About pollen in Pomona

Pollen levels around Pomona are quiet today, with weeds providing the only real activity worth mentioning. Tree pollen is essentially absent, and weed pollen sits at a low level, so most people should get through the day without much irritation. Those especially sensitive to weed pollen might notice mild effects, but overall this is an easy day for allergy sufferers. Looking ahead, expect this pattern to hold steady, with weed pollen remaining low and steady over the next several days while trees stay dormant. This lines up with the season: late summer in Southern California typically means a lull for trees like albizia, tristaniopsis, pyrus, maple, and hickory, which had their more active stretch back in spring, while weeds continue their gradual presence through the warmer months. Grass isn't a factor right now either, so overall conditions should stay mild and consistent through the week.
