Moderate Pollen in Aurora, CO

About pollen in Aurora

Grass pollen is the main driver in Aurora today, sitting at a moderate level on the Universal Pollen Index while the overall reading also lands at moderate. Tree pollen has fallen back to very low, so the area's typical allergenic species — Linden, Celtis, Ash, Oak, and Maple — are contributing little at this point. The five-day outlook shows steady conditions, with grass holding at moderate and tree pollen staying very low throughout. That pattern fits the late-spring into early-summer window, when grass tends to dominate after the spring tree season winds down. Weed pollen data isn't available right now, though ragweed generally becomes a factor later in summer and into fall.

What to do today

• It's important to shower and wash your hair after spending a lot of time outdoors.

• Wash clothes worn outdoors to remove any remnants of pollen grains.
• If possible, wear glasses instead of contact lenses.
• Did you hang any laundry outside? Now is a good time to hang clothes indoors or use a dryer if possible.
