Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Bloomington today, sitting at a moderate level and pushing the overall index to moderate as well. Tree pollen has dropped to very low, so local species like Oak, Ash, Celtis, Maple, and Pine are contributing little at this point in the season. That timing fits late June, when the spring tree peak has passed and grasses dominate early-summer counts. The forecast points to a gradual easing, with grass slipping from moderate toward low over the next several days while tree pollen holds steady at very low. Weed pollen data isn't available right now.
