About pollen in Deer Valley

Weed pollen is the main driver of discomfort in Deer Valley today, running high and likely to affect anyone with sensitivities. Grass pollen adds to the mix at a moderate level, noticeable but generally more manageable. Tree pollen is absent, so those with tree-related sensitivities should get a break for now. Looking ahead, weed pollen is expected to climb even further over the next several days, while grass holds fairly steady before ticking up slightly toward the end of the period. Tree pollen should remain quiet throughout, consistent with this time of year, since local trees like mesquite and olive typically shed their pollen in spring rather than fall. This pattern fits the season well: early autumn in the desert Southwest is prime time for ragweed and other weeds, so those sensitive to weed pollen should expect symptoms to linger or intensify in the coming days.

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).
