About pollen in Tempe Junction

Weed pollen is the main driver of today's conditions in Tempe Junction, running high and likely to affect those with sensitivities. Grass pollen is also present at a moderate level, adding to the overall load, while tree pollen is quiet with nothing active at the moment. Combined, this makes for a day when allergy symptoms could be more noticeable than usual, particularly for anyone sensitive to weeds. Looking ahead, weed pollen is expected to stay high through the next few days and edge up further by the end of the period, consistent with the late-summer-into-fall pattern when ragweed and related weeds are typically most active in the region. Grass pollen should remain steady at a moderate level before a slight increase later in the forecast window. Tree pollen is expected to stay absent, which is typical for this time of year since local trees such as mesquite and olive generally release most of their pollen in spring rather than fall.

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).
