About pollen in Chandler

Weed pollen is dominating the air in Chandler today, reaching a level that is likely to bother even those with mild sensitivities. Grass pollen is also present at a moderate level, which may add to the discomfort for people who react to multiple pollen types. Tree pollen is quiet, so it is not a factor right now. Looking ahead, this pattern is expected to hold steady over the next several days, with weed pollen remaining very high and grass staying at a moderate, noticeable level. This lines up with the season, as late summer into fall is prime time for ragweed and other weeds across the desert Southwest, while local trees like mesquite, olive, and palo verde are well past their pollen-producing period until spring returns.

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.
