About pollen in Waukegan

Pollen levels in Waukegan are quiet today, with both tree and weed sources reading very low. Grass isn't registering at all right now. Most people should be able to get outside comfortably, and even those with sensitivities are unlikely to notice much in the way of symptoms. Looking ahead, weed pollen is expected to tick upward over the next several days, moving from very low toward a more moderate range, while tree pollen stays mild throughout. This shift lines up with the season — mid-August is when ragweed and other late-summer weeds start becoming more active in the region, a trend that typically continues into fall. Tree pollen from species like oak and maple is well past its spring peak, so it should remain a minor factor for now. If you're sensitive to weed pollen, it may be worth keeping an eye on conditions as the week progresses.
