About pollen in Portsmouth Heights

Weed pollen is the main concern in Portsmouth Heights today, running high and likely to cause noticeable symptoms for those who are sensitive to it. Tree and grass pollen, by contrast, are both very low and shouldn't cause much trouble. If you tend to react to ragweed and similar late-season weeds, it may be worth limiting time outdoors during peak afternoon hours or keeping windows closed. Looking ahead, this pattern is expected to hold steady over the next several days, with weed pollen remaining high while tree and grass levels stay minimal. This lines up with the typical seasonal calendar for late September, when ragweed and other weeds dominate the pollen picture in the region. Tree pollen from species like oak, maple, and pine has long since wound down for the year and won't pick back up until spring, so weed exposure is the one to plan around for 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).
