About pollen in Sioux City

Pollen activity in Sioux City is quiet at the moment, with nothing significant standing out across trees, grasses, or weeds. This should make for an easy stretch for most allergy sufferers, though those with heightened sensitivity may still notice occasional mild irritation on breezy days when local dust and residual pollen get stirred up. Looking ahead, late July typically marks a lull between the grass pollen that dominates late spring and early summer and the ragweed season that ramps up in late summer through fall. Area trees such as oak, elm, and cottonwood finished their heavier pollen release months ago, so tree pollen is not a concern right now. As August approaches, it is worth watching for the return of ragweed, which tends to become the main driver of symptoms once late summer arrives in this part of Iowa.
