About pollen in Ann Arbor

Grass pollen is the main driver in Ann Arbor today, sitting at a Low level (2) and accounting for the overall Low reading. Tree pollen has dropped to Very Low (1), which fits the seasonal pattern now that the spring surge from regional trees like oak, birch, and maple has wound down. Looking ahead, grass is expected to tick up to the moderate range over the next couple of days before easing back toward Low later in the forecast window. Tree levels should hold steady at Very Low throughout. This is typical for late June, when grass tends to dominate; weed pollen, including ragweed, generally becomes a factor later in summer and into fall. No weed data is available at this time.
