About pollen in Hialeah

Weed pollen is the main driver of today's conditions in Hialeah, with levels running high enough to cause noticeable symptoms for those who are sensitive. Grass pollen is present as well, though at a much lower, generally mild level. Tree pollen is quiet and not a factor right now. Looking ahead, this pattern should hold steady through the next several days: weed pollen is expected to stay high, grass will remain low but steady in the background, and tree pollen should continue to be a non-issue. This lines up with the seasonal calendar, as late September falls squarely within ragweed and other weed pollen season in South Florida, while the typical local trees, such as oak, pine, and palm, are well past their spring peak and not contributing much right now.

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).
