Very low today, mostly tree pollen.
Last updated July 8, 2026
Pollen levels in Bloomington are quiet today, with both tree and grass sources registering very low. Neither is likely to cause much trouble, even for those who are typically sensitive to oak, ash, or maple in the spring or to grasses later in the season. It's a comfortable day to be outdoors from an allergy standpoint. Looking ahead, the next several days should bring more of the same, with tree and grass pollen expected to stay at low levels through the week. This lull fits the season, as the major spring tree pollen from species like oak, ash, celtis, maple, and pine has largely wound down, and grass pollen, while still present into early summer, isn't showing much activity right now either. Ragweed season is still a ways off, so overall this is a relatively easy stretch for allergy sufferers in the area.
