Pollen in Pomona, CA

About pollen in Pomona

Pomona's air is essentially clear of pollen today. Tree pollen, the only category being measured right now, is reading at none, so anyone prone to seasonal allergies should find little to react to. It's a good stretch for outdoor plans, with no notable irritation expected from the trees around the area. Looking ahead, conditions are expected to stay quiet, with tree pollen holding at none through the near-term forecast. This fits the time of year, since local species such as Albizia, Tristaniopsis, Pyrus, Maple, and Hickory typically stay dormant through late fall and won't begin releasing pollen in earnest until closer to spring. For now, there's little reason to expect any seasonal allergy symptoms tied to tree pollen.
