Statewide allergy overview
Mississippi experiences a humid subtropical climate with long, hot, humid summers and short, mild winters.
Oak, pine, cedar, and pecan create an intense, early spring tree season — sometimes coating cars in yellow pine pollen by March. Bermuda and Bahia grass pollinate from late spring through fall, and ragweed dominates the late-summer weed load.
Year-round humidity makes the Southeast one of the highest mold-load regions in the country, with Cladosporium and Alternaria peaking after summer thunderstorms and tropical systems.
Allergy patterns vary by elevation and proximity to coast or mountains within Mississippi, but most of the state shares a common seasonal rhythm of spring tree pollen, summer grass pollen, and late-summer to fall weed pollen.
