About pollen in Plano

Pollen levels are high across the board in Plano today, with tree and weed pollen both pushing into territory that is likely to bother sensitive individuals, while grass pollen runs at a more moderate but still noticeable level. Anyone who tends to react to ragweed or fall tree pollen should expect symptoms to be fairly pronounced, especially if spending extended time outdoors. Looking ahead, conditions should ease briefly, with a lull expected in a couple of days before pollen picks back up again toward the end of the stretch. This pattern fits the season: late September in North Texas is prime time for ragweed and other fall weeds, which explains today's elevated weed count, while lingering tree pollen at this time of year is more unusual and likely reflects a mix of late-season stragglers rather than the oaks, elms, and pecans that dominate the spring bloom. Grass pollen, meanwhile, is holding at a steady moderate level and should continue fluctuating modestly through the week.

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).
