Omaha Pollen Report
Omaha sits in the Missouri River valley at the heart of the Great Plains, and its allergy seasons are full-strength Midwest. Oak and elm hammer the metro in spring, grasses run through a hot, windy summer, and fall ragweed counts are among the heaviest in the region. River-bottom humidity keeps mold in the mix through every wet stretch.

What drives allergies in Omaha
Trees: oak, elm, and ash (March – May)
Oaks (Quercus), elm, and ash drive the spring season, with cottonwood adding pollen along the Missouri corridor in late spring.
Grasses: fescue and bluegrass (May – July)
Lawn and pasture grasses peak in June, with hot, windy plains weather spreading pollen across the metro.
Weeds: ragweed (August – frost)
Nebraska is prime ragweed country. Common and giant ragweed (Ambrosia) fill field edges, riverbanks, and disturbed lots, and fall counts stay high until a hard frost.
Mold: humid river valley
Missouri Valley humidity keeps Alternaria and Cladosporium active all summer, with spikes after storms and during fall harvest.
