What is driving Ko Olina’s pollen today

The shape of today’s 19 (Low) is set by weed pollen at 20 (Low on its own scale) — about 39% of the four category readings added together, 4 points clear of the next category, grass pollen at 16. A weed-led total is the classic late-year shape: tree and grass pollen have usually receded, leaving weed pollen — and on damp days mold — to make up most of what the index records. Weed pollen leading in November is the Hawaii calendar working as expected — November falls in the opening weeks of the state’s weed chapter.

Plant-level detail is not in today’s feed for Ko Olina, so the drivers have to be read from the category split above. The Hawaii guide’s account of Hawaii names kiawe, flowering most heavily in late winter and spring, and grasses that pollinate in nearly every month — the pollens behind readings of this shape in this state — and the split shows how much of today’s total each category is actually carrying.

Across the five-day window the Total Pollen Index runs from 19 to 23, never changing band. Today’s 19 sits 1 point below the window’s average of 19.8 — a steady window, in which one day reads much like the next.

Ko Olina pollen through the year

Chapter by chapter, the Ko Olina pollen year runs like this:

• Kiawe, the signature tree of the dry leeward lowlands, flowers most heavily in late winter and spring, in overlapping waves rather than a single spring flush.
• Grasses pollinate in nearly every month, with the strongest run from spring into summer and a peak from March through August.
• The guides name no separate weed chapter for Hawaii — the year is carried by grasses, tree waves and wet-season mold.
• The wet season, roughly November through April, shifts the burden toward mold and indoor damp even as outdoor pollen eases in places.

The Hawaii allergy season guide names kiawe, flowering most heavily in late winter and spring, and grasses that pollinate in nearly every month. Hawaii has no frost and no true off-season: grasses pollinate in nearly every month, with the strongest grass run from spring into summer. Windward towns trade some dry pollen for persistent damp and mold, while leeward towns trade mold for dust, grass pollen and, on Hawaii Island, vog.

November in Ko Olina sits in the overlap of the grass and weed chapters of the Hawaii year — overlap weeks, when two chapters feed the same total and the split matters more than the headline. Between them, the three chapters touch every month of the Hawaii year — there is no reliably empty month in this calendar. The full calendar is set out in the Hawaii allergy season guide.

How to read this index

Pollen Atlas reports the Ko Olina pollen count on a Total Pollen Index from 0 to 100, built from separate tree, grass and weed readings. The total is a summary, not an average of the three: a single strong category can lift it, and three quiet categories can hold it down even in a month when Ko Olina, HI pollen is usually more active. Index values are a modelled pollen risk index computed by Pollen Atlas from open weather, vegetation and phenology data, calibrated against CDC/NAB season data, with plant detail by the Google Pollen API. The index is a modelled 0–100 scale, not a measured count, and figures update through the day, so a morning and an evening visit to this page can legitimately show different numbers.
