About pollen in Boca Raton

Weed pollen is the main driver of today's conditions in Boca Raton, and it is running high enough to be noticeable for those who deal with seasonal sensitivities. Grass pollen is present but at a low level, while tree pollen is essentially quiet. For most people, any irritation today is likely to trace back to ragweed and similar weeds rather than trees or grasses. Looking ahead, that pattern should hold steady over the next several days, with weed pollen remaining high and grass staying in the low range. Tree pollen may tick up slightly but will likely stay minimal throughout the stretch. This lines up with the time of year — early fall in South Florida is typically ragweed season, while the live oaks, pines, and other trees common to the area remain largely dormant until closer to spring.

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).
