About pollen in Clearwater

Weed pollen is the main driver of discomfort in Clearwater today, running high enough that sensitive individuals will likely notice symptoms such as sneezing or itchy eyes. Grass pollen is also active at a moderate level, adding to the overall load, while tree pollen remains low and should have little impact for most people. Looking ahead, weed pollen is expected to stay high over the next couple of days before gradually tapering toward the end of the five-day period. Grass pollen should hold at a similar moderate level before easing later in the week, and tree pollen is likely to stay low throughout. This pattern fits the season well, as late September marks the height of ragweed and other weed pollen activity in Florida, while trees such as oak and pine typically remain quiet until their spring peak.

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).
