About pollen in Naperville
Grass pollen is the main driver in Naperville today, sitting at a Low level (2) and leading an overall index that also reads Low. Tree pollen has dropped to Very Low (1), so it's a minor factor at the moment. The forecast keeps grass steady at Low for the next few days before easing toward the lower end of that range, while tree pollen holds at Very Low throughout. That pattern fits late June, when the spring surge from regional trees like oak, birch, and maple has faded and grasses become the seasonal mainstay. Ragweed and other weed pollen, which typically picks up later in summer and fall, has no data reported here today.
