About pollen in Chattanooga

Weed pollen is the main driver of today's pollen picture in Chattanooga, sitting at a moderate level that could be noticeable for those who are sensitive. Tree and grass pollen are both very low and unlikely to cause much trouble. Overall, it's a fairly manageable day, though anyone prone to weed allergies may notice some mild symptoms outdoors. Looking ahead, weed pollen is expected to climb slightly, reaching a high level tomorrow before gradually easing over the following days and dropping off entirely by the end of the forecast period. Tree and grass pollen should stay low and steady throughout. This pattern is typical for late September, when ragweed is the dominant allergen of the season, while pollen from trees like oak and maple remains dormant until their spring release.

What to do today

  • It's important to shower and wash your hair after spending a lot of time outdoors.

  • Wash clothes worn outdoors to remove any remnants of pollen grains.
