About pollen in Allentown

Weed pollen is the main driver of today's conditions in Allentown, sitting at a moderate level that could be noticeable for those who tend to react to it. Tree pollen remains quiet in the background, so anyone with sensitivities is more likely to feel the effects of weeds than trees at this point in the season. Looking ahead, weed pollen is expected to ease slightly tomorrow before climbing back into the moderate range for the following few days, so sensitive individuals may want to plan accordingly later in the week. Tree pollen should stay low throughout, consistent with mid-August, since the oak, maple, and birch trees common to the region finished their pollen release back in spring. This pattern fits the typical late-summer stretch, when ragweed and other weedy plants take over as the primary source of pollen in the area.

What to do today

  • It's important to shower and wash your hair after spending a lot of time outdoors.
  • When spending time outside, use sunglasses and a cap to keep pollen out of your face and eyes.
  • 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.
