Pollen count Captain Cook residents check each morning
The Captain Cook pollen count today is 17 (Low). The main driver is Ragweed, with weed pollen at 16 today. Tree pollen is the highest single category in the split at 18 (Low), ahead of weed pollen at 16 and grass pollen at 14. The sections below break that headline number down by plant, by day and by what the band means in practice. Pollen Atlas updated this count on Friday, November 6, 2026.
A Low band on the Pollen Atlas index means the Total Pollen Index has stayed in the lower part of the 0–100 scale. Readings in this band are built from low individual category values rather than from one large spike, and the category split above matters more than the headline number: a low total can still contain one category, such as tree pollen, reading noticeably higher than the rest, which is why the split is printed on every Captain Cook page.
Fall is ragweed season across most of the United States: ragweed plants release pollen from late summer into autumn, and weed pollen is typically the last major outdoor pollen category to fade as the weather cools. That pattern is why an autumn total is so often weed-led even when the headline number is low — tree and grass pollen have usually receded by then, leaving weed pollen, and on damp days mold, to make up most of what the index records.

Pollen by type in Captain Cook
What is driving Captain Cook’s pollen today
The shape of today’s 17 (Low) is set by tree pollen at 18 (Low on its own scale) — about 38% of the four category readings added together, 2 points clear of the next category, weed pollen at 16. Tree readings are the fastest-moving of the four in their season, because species pollinate in sequence — a tree-led total can change character within a week. Tree pollen leading in November runs against the usual calendar — the Hawaii tree chapter runs February to May — so today’s lead is the model outranking the pattern, and this page reports the modelled reading first.
Plant-level detail is not in today’s feed for Captain Cook, 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 13 to 17, never changing band. Today’s 17 sits 2 points above the window’s average of 15.4 — a steady window, in which one day reads much like the next.
Plants affecting Captain Cook now
Detailed plant-by-plant readings for Captain Cook were not returned in today\u2019s source data, so this section summarises the pollen types the index above is built from instead of listing individual plants.
Tree pollen is one of the categories with a non-zero reading today, at 18 (Low).
Grass pollen is one of the categories with a non-zero reading today, at 14 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 16 (Low).
In the Hawaii pattern, the plants that typically shape this city’s year are grasses that pollinate in nearly every month and kiawe flowering most heavily in late winter and spring, with mold in the wet season — named here as regional context only, not as today\u2019s measurements.

Captain Cook pollen through the year
The Captain Cook pollen year runs in chapters, set by its own pattern and the Hawaii calendar. Trees come first: 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 take the middle of the year: grasses pollinate in nearly every month, with the strongest run from spring into summer and a peak from March through August. Weeds close it out: 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 Captain Cook 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 Captain Cook 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 Captain Cook, 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.

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Captain Cook resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every ragweed season, allergists in Captain Cook, HI can test whether tree, grass, weed or mold is the category that matters for you — the four readings at the top of this page are the starting point for that conversation.
