About pollen in Waukegan

Pollen levels in Waukegan are low across the board today, with tree and weed pollen roughly even and unlikely to cause much trouble for most people. Those with sensitivities may notice a mild effect, but overall it should be an easy day to spend outside. Looking ahead, conditions are expected to stay generally mild over the next several days, though weed pollen is likely to tick upward toward the end of the period as late-summer ragweed activity begins to build. Tree pollen, already well past its spring peak from species like oak and maple, should remain a minor factor throughout. As August progresses, keep an eye on weeds, since ragweed tends to become the dominant source of pollen through the fall.
