Pollen Count & Forecast for Kansas City

Kansas City’s spring (March-May) is dominated by Oak (Quercus); prolific in Swope Park and Loose Park. Eastern Red Cedar (Juniperus virginiana) is dense around Wyandotte County Lake; Maple (Acer) is frequent in the Brookside area. Summer (May-July) has high Timothy Grass (Phleum pratense) levels, originating from Penn Valley Park and Missouri River floodplains. Late summer has Ragweed (Ambrosia) along Kansas River banks.

The Missouri and Kansas River valleys trap humidity and allergens; low-lying basins have high pollen density. Autumn and winter have high Mould (Alternaria, Cladosporium) spore counts; these are from decaying leaf litter in Kessler Park and damp suburban gardens.
