About pollen in Deltona

Weed pollen is the main concern in Deltona today, running high and likely to cause noticeable symptoms for those who are sensitive. Grass pollen adds to the mix at a moderate level, while tree pollen remains low and should pose little trouble for most people. Looking ahead, this pattern is expected to hold steady over the next several days, with weed pollen staying high and grass fluctuating between low-moderate and moderate levels. Tree pollen should continue to stay quiet throughout the period. This lines up with the season, as late September marks a peak time for ragweed and other weeds in Florida, while trees such as oak and pine remain far from their spring highs.

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).
