About pollen in Ann Arbor

Both tree and weed pollen are running at a moderate level in Ann Arbor today, making this the kind of day sensitive individuals are likely to notice some effect, while most other people should get through it without much trouble. Neither category dominates the air right now, so it is more of a steady, mild irritation than a sharp spike. Looking ahead, this moderate pattern is expected to hold fairly steady over the next several days, with tree pollen easing slightly before ticking back up and weed pollen staying consistently present throughout the stretch. This lines up with the season, as August marks the start of ragweed's active period, one of the more common weed pollens in the region, while lingering tree pollen at this point in summer is typically the tail end of activity from species like oak and hickory rather than a fresh surge. Overall, conditions should remain manageable, but it is a reasonable stretch to keep allergy remedies within easy reach.
