About pollen in Avondale

Weed pollen is the main driver of today's high overall count in Avondale, with grass close behind at a moderate level. Anyone sensitive to ragweed and related weeds should expect noticeable symptoms outdoors, while grass exposure may add mild irritation on top of that. Tree pollen is quiet for now, so it isn't a factor in today's conditions. Looking ahead, this pattern should hold steady over the next several days, with weed levels remaining high and grass staying moderate throughout the stretch. This lines up with the season, as late summer into fall is peak time for weed pollen like ragweed across the desert Southwest, while typical local trees such as mesquite, olive, and ash are well past their spring pollen release and won't contribute meaningfully right now.

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).
