About pollen in Sioux City

Grass pollen is the main driver in Sioux City today, sitting at a low level on the Universal Pollen Index, which keeps overall conditions modest. The five-day outlook shows grass holding steady at that same low reading, so expect little change in the days ahead. This fits the season, as grass pollen typically runs highest in late spring and early summer, when late June falls. Tree pollen, which usually peaks earlier in spring, has no data to report today, and weed pollen — driven by ragweed later in summer and fall — is similarly unmeasured here. For now, the grassy backdrop is the only notable factor, and it remains on the low end.
