Statewide allergy overview
Alaska experiences a subarctic to arctic climate with long, cold winters and short, cool summers.
Birch dominates the late-spring and early-summer tree season — birch pollen counts in south-central Alaska are among the highest in North America. Grass pollen peaks briefly in June and July.
Mold counts spike during the brief summer growing season and after fall decay.
Allergy patterns vary by elevation and proximity to coast or mountains within Alaska, but most of the state shares a common seasonal rhythm of spring tree pollen, summer grass pollen, and late-summer to fall weed pollen.
