Low Pollen in Aurora, CO

About pollen in Aurora

Weed pollen is the main contributor to Aurora's air today, though levels remain low enough that most people won't notice much effect. Tree pollen is barely registering at this point in the year, so any irritation is far more likely to trace back to lingering weeds than to trees like ash, maple, oak, honeylocust, or elm, all of which are well past their active season. Looking ahead, weed pollen is expected to ease slightly and settle into a steady, low pattern over the next several days, making for generally comfortable conditions. Tree pollen should stay quiet throughout, consistent with the fall season, as local trees have already finished their spring release and won't become active again until next year. Overall, this is a calm stretch for allergy sufferers in the area.
