Kansas City Pollen Report
Kansas City sits where eastern hardwood forest meets tallgrass prairie — and it gets allergy seasons from both worlds. Oak and hickory hammer the metro in spring, prairie and lawn grasses run all summer, and Kansas City is squarely in ragweed country come fall. Humid air off the Missouri and Kansas rivers keeps mold counts up through every warm, wet stretch.

What drives allergies in Kansas City
Trees: oak, hickory, and elm (March – May)
Oaks (Quercus) are the metro's dominant spring allergen, with hickory, elm, and maple adding to the load. April is usually the roughest month.
Grasses: fescue and Bermuda (May – August)
Tall fescue lawns and native prairie grasses pollinate heavily in early summer; hot, windy June days are the peak.
Weeds: ragweed — the Midwest's main event (August – frost)
Kansas City is deep in ragweed country. Common and giant ragweed (Ambrosia) blanket roadsides and fields, and fall counts rank among the highest in the region.
Mold: humid summers, leaf-filled falls
River-valley humidity keeps Alternaria and Cladosporium active all summer, with big spikes after storms and during autumn leaf drop.
