No notable pollen right now.
Last updated July 21, 2026
Pollen levels in Madison are quiet today, with tree pollen essentially absent. Sensitive individuals should get a welcome break, as there is little in the air to trigger symptoms right now. Looking ahead, tree pollen is expected to remain at this low level over the next several days, which fits the season well. Trees such as linden, elm, ash, crabapple, and hazelnut had their peak activity back in spring, so this summer lull is typical. As the season progresses, keep in mind that grass pollen tends to be more relevant in early summer, while ragweed becomes the focus later in the season.
