Pollen count Waikapu residents check each morning
The Waikapu pollen count today is 20 (Low). The main driver is Ragweed, with weed pollen at 20 today. Grass pollen is the highest single category in the split at 20 (Low), ahead of weed pollen at 20 and tree pollen at 19. Below, the plant detail and the multi-day outlook show whether today is the pattern or the exception. Pollen Atlas updated this count on Saturday, November 7, 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 grass pollen, reading noticeably higher than the rest, which is why the split is printed on every Waikapu 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 Waikapu
What is driving Waikapu’s pollen today
The shape of today’s 20 (Low) is set by grass pollen at 20 (Low on its own scale) — about 34% of the four category readings added together, level with weed pollen at 20. Grass-led totals tend to hold a level for days at a time rather than spike and clear, because grasses pollinate over an extended period. Grass pollen leading in November is the Hawaii calendar working as expected — November falls in the heart of the state’s grass chapter.
Plant-level detail is not in today’s feed for Waikapu, 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 20, never changing band. Today’s 20 sits 0 points above the window’s average of 19.8 — a steady window, in which one day reads much like the next.

Waikapu pollen through the year
Three chapters make the Hawaii pollen year, and Waikapu follows them in the state’s own order. The tree chapter: 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. The grass chapter: grasses pollinate in nearly every month, with the strongest run from spring into summer and a peak from March through August. The weed chapter: 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.
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. The Hawaii guide singles out kiawe, flowering most heavily in late winter and spring, and grasses that pollinate in nearly every month.
November in Waikapu 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 Waikapu 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 Waikapu, 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.
