Pollen Count & Forecast for Omaha
About Pollen in Omaha
Omaha’s spring allergy season (March-May) is dominated by Oak and Maple pollen; Oak (Quercus) common in Fontenelle Forest; Maple (Acer) widespread across Elmwood Park. Birch (Betula) contributes to counts in residential areas. Summer (May-July) has high Grass (Poaceae) levels, originating from Missouri River floodplains. Autumn (August-October) has high Ragweed (Ambrosia) levels from surrounding prairies.
The Missouri River valley traps airborne particles; wind from the open plains moves pollen into city centers. Autumn has high Mould (Alternaria, Cladosporium) spore counts; these come from decaying leaf litter in Lauritzen Gardens and damp riverbank soils. High summer humidity maintains indoor spore levels.
