About pollen in Allen

Pollen levels are quite high in Allen today, with tree pollen leading the way and weed pollen close behind. Anyone sensitive to airborne allergens is likely to notice symptoms outdoors, especially in the morning and early afternoon when pollen tends to concentrate. Grass pollen is also present at a moderate level, adding to the overall load, so those with multiple sensitivities may feel the effects more than usual. Looking ahead, tree and weed pollen should stay elevated for the next day or so before easing later in the week, while grass pollen holds fairly steady before also tapering off. This pattern fits the season: late September often brings a lingering mix of tree pollen from species like cedar and elm alongside the tail end of ragweed and other weed pollen, which typically peaks in late summer and into fall. As the week progresses, conditions are expected to become more comfortable for those affected by pollen.

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).
  • Make sure to use an air purifier with HEPA filter in your home, especially in your bedroom. Don't forget to perform regular filter maintenance checks.
