Fraxinus pennsylvanica
Very low today, mostly tree pollen.
Last updated July 28, 2026
Pollen levels around Bloomington are quiet today. Tree pollen, the only type registering any activity, sits at a very low level, meaning most people should be able to spend time outdoors without noticing much effect from it. Even those who are sensitive to tree species like oak, maple, or juniper are unlikely to find today particularly bothersome. Looking ahead, the next several days should bring more of the same, with tree pollen expected to remain very low throughout the stretch. This lull fits the season well: the heavier tree pollen releases from species such as oak, maple, juniper, celtis, and juglans typically wind down after spring, leaving summer as a calmer period before ragweed and other late-season weeds tend to pick up in the fall.
