We're seeking a pollen partner in Hawaii.
PollyMap doesn't publish cheap forecast estimates — the kind that guess what might be in the air and are often wrong by the time you read them. Every report on PollyMap is real airborne pollen and mold, captured by a PollyKit air sampler and counted under a microscope by a trained local partner.
We're actively seeking an allergy clinic or qualified collector to become the Official PollyMap Partner for Hawaii. Exclusive territory, weekly content, and AI-assisted analysis included.
Pollen patterns across Hawaii
Grass pollen — especially Bermuda, paspalum, and Johnson grass — is the dominant year-round trigger. Tree pollen is less seasonal than on the mainland, with eucalyptus, mango, and ironwood active throughout the year.

Frequently asked questions
When is allergy season in Hawaii?
Allergy season in Hawaii typically runs from late winter through fall. Tree pollen rises first, followed by grass pollen in late spring and early summer, and weed pollen (especially ragweed) in late summer and fall.

In Hawaii, the highest-pollen species are typically Eucalyptus, Ironwood, Mango in spring, Bermuda grass in early summer, and Plantain in fall.

For most people, April and May (tree pollen) and September (ragweed) are the most difficult months in Hawaii, with grass pollen creating a third peak in June.
