Honolulu's allergy season varies with proximity to the coast. Coastal breezes help, but residents of Honolulu, HI can still experience significant pollen from February through October, especially during dry, warm spells.
Right now: March is heavy tree pollen month in Honolulu. Multiple tree species overlap, driving counts high.
Spring

Tree pollen starts early — alder, birch, and oak are primary triggers.

Fall

Ragweed and sagebrush in drier areas. Coastal cities see lower counts.
Ocean breezes near Honolulu can help clear pollen, but inland valleys trap allergens. Wildfire season also degrades air quality significantly. PollenTracker monitors both pollen and AQI to give you the full picture.
