About pollen in Chicago
Pollen levels around Chicago are quiet today, with both tree and weed sources registering at very low levels. Most people should be able to move through the day without much irritation, and even those who tend to be sensitive are unlikely to notice much of an effect. Looking ahead, tree pollen should stay minimal through the next several days, which fits the season since local trees like oak, maple, and ash have long since finished their spring release. Weed pollen, on the other hand, is expected to inch up slightly from very low to a mild, noticeable range later in the week. This lines up with the typical late-summer pattern, as ragweed and other weeds begin to stir ahead of their fall peak. Overall, conditions remain easy for most of this week, with only a modest uptick worth keeping in mind.
