High Pollen in Tri-Cities, WA

About pollen in Tri-Cities

Weed pollen is running high across Tri-Cities today, and it's the main source of irritation in the air. Anyone sensitive to ragweed and similar late-season weeds should expect noticeable symptoms if spending time outdoors, particularly during the afternoon hours when pollen tends to circulate most freely. Looking ahead, weed pollen is expected to climb even further over the next several days, holding at a very high level through the coming week. This lines up with the typical seasonal pattern for the region, as ragweed and other weeds dominate the pollen picture in early autumn, well after the spring tree pollen from species like alder, birch, and juniper has faded and the grass pollen of early summer has tapered off. With weed levels staying elevated, it's a good stretch to plan outdoor time with that in mind.

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).
