High Pollen in Greensboro, NC

About pollen in Greensboro

Weed pollen is the main story in Greensboro today, running high enough to bother most sensitive individuals who spend time outdoors. Grass pollen is low and tree pollen is barely registering, so if you're feeling symptoms this time of year, weeds are almost certainly the cause. That pattern should hold steady through the next several days, with weed pollen staying high before easing somewhat toward the end of the stretch. This lines up with the typical fall pattern, as ragweed and other late-season weeds move into their most active phase. Tree pollen from species like oak, pine, maple, ash, and hickory remains quiet, as expected outside of their spring release, and grass is likely to stay in the background as well.

What to do today

• Avoid mowing the lawn and raking leaves.
• When driving the car, close your windows and turn the air conditioning system to recirculation mode.
• Keep your windows closed and turn on your air purifier or air conditioning.
• Consider staying indoors during the peak pollen hours (morning and early afternoon).
