About pollen in Scottsdale

Weed pollen is the main concern in Scottsdale today, running high and likely to cause noticeable symptoms for those who are sensitive. Grass pollen is also active at a moderate level, which can add to the discomfort, while tree pollen is essentially quiet right now. Looking ahead, this pattern is expected to hold steady over the next several days, with weed pollen actually climbing a bit higher by midweek before easing slightly. Grass pollen should remain at a consistent moderate level throughout the stretch. This lines up with the season, as autumn in the desert Southwest is prime time for weeds like ragweed to thrive, while trees such as mesquite and olive typically stay dormant until spring brings their pollen back into play.

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).
