High Pollen in Knoxville, TN

About pollen in Knoxville

Weed pollen is the main concern in Knoxville today, running high enough to cause noticeable symptoms for anyone with sensitivities. Tree and grass pollen, by contrast, are barely registering and shouldn't cause much trouble. If you tend to react to ragweed this time of year, today is likely to feel the most irritating part of your week. Looking ahead, weed pollen is expected to stay high over the next couple of days before gradually tapering toward the weekend, offering some relief by the final day of the forecast. Tree and grass levels should remain low and steady throughout, which tracks with the season — local trees like elm, oak, maple, zelkova, and carpinus typically release their pollen in spring, so their quiet activity now is normal. Ragweed and other late-season weeds are the more typical culprits this time of year, and that pattern is exactly what's playing out this 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).
