Statewide allergy overview
Kentucky experiences a humid subtropical to humid continental climate with warm, humid summers and mild to cold winters.
Oak, birch, cedar, maple, and pine drive a long March-through-May tree season. Grass pollen is heaviest in May and June, and ragweed extends through October.
High summer humidity and dense forest cover produce sustained high mold counts from June through frost.
Allergy patterns vary by elevation and proximity to coast or mountains within Kentucky, but most of the state shares a common seasonal rhythm of spring tree pollen, summer grass pollen, and late-summer to fall weed pollen.
