About pollen in Maryvale

Weed pollen is the main story in Maryvale today, running high enough to cause noticeable symptoms for those who are sensitive. Grass pollen is also active at a moderate level, adding to the overall load, while tree pollen is quiet with nothing significant in the air right now. Looking ahead, grass levels should hold fairly steady over the next few days before ticking up slightly toward the end of the period, and weed pollen is expected to stay high with a further increase likely by the fifth day. This pattern fits the season, as late summer into fall is peak time for weeds like ragweed in the desert Southwest, while grasses continue to linger. Tree pollen typically stays low through this stretch of the year, with species such as mesquite, olive, and ash not becoming active again until spring.

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).
