About pollen in Arlington

Pollen levels are running high across the board in Arlington today, with tree and weed pollen both pushing into the bothersome range and grass close behind at a moderate level. If you tend to react to airborne pollen, today is likely to bring noticeable symptoms, particularly from tree and weed sources working together. Looking ahead, expect some relief by midweek as tree and weed levels ease off substantially before climbing back up toward the end of the five-day stretch. Grass pollen is set to stay fairly steady throughout, hovering between moderate and high. This pattern fits the season—weeds like ragweed are typically most active in late summer into fall, while any lingering tree pollen this time of year, from sources such as oak, elm, and hickory, tends to be more sporadic than the heavy spring peaks. Those sensitive to multiple pollen types should be prepared for a bumpier few days ahead, with the clearest stretch likely mid-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).
