About pollen in Arlington

Weed pollen is the main driver of today's allergy conditions in Arlington, with levels running high. Anyone sensitive to ragweed and similar late-season weeds should expect symptoms to be fairly noticeable, especially outdoors during the afternoon. Tree pollen is absent right now, so those with tree-related allergies can expect a reprieve on that front. Looking ahead, weed pollen should ease over the next couple of days before settling into a milder, more tolerable range by midweek. This pattern fits the season well: early October is typically when ragweed and other fall weeds wind down their peak activity. Tree pollen from species like oak, maple, and the Prunus and Malus family is not a concern at this time of year and won't become active again 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).
