Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Milwaukee today, sitting at a low level of 2 on the index, while tree pollen has dropped to very low at 1. The forecast holds steady through the coming days, with grass staying at 2 for most of the stretch before easing to 1, and tree pollen flat at 1 throughout. This is typical for late June, when the spring tree season—including local sources like ash, maple, honeylocust, and syringa—has largely wound down and grasses take over as the seasonal high point. Overall conditions remain low at 2, so expect modest grass-driven activity without much fluctuation in the near term.
