Statewide allergy overview
Texas experiences a wide range of climates from humid subtropical in the east to semi-arid in the west, with hot summers and mild winters statewide.
Mountain cedar (Ashe juniper) produces a notorious December-through-February allergy season known as 'cedar fever'. Oak follows in spring, Bermuda grass pollinates through summer, and ragweed peaks in fall.
Humid Gulf air keeps mold counts elevated most of the year, with sharp spikes after thunderstorms.
Allergy patterns vary by elevation and proximity to coast or mountains within Texas, but most of the state shares a common seasonal rhythm of spring tree pollen, summer grass pollen, and late-summer to fall weed pollen.
