Pollen Atlas models the daily detail as an overall index: day-by-day splits by individual pollen type are not part of the modelled data, so this table shows Kalaheo’s overall trend across the week. Today’s ragweed pollen reading is the headline above.

Species driving Kalaheo’s ragweed pollen

Species-level counts are not part of the modelled data Pollen Atlas publishes — the modelled index is reported per pollen type, not per species — so this section gives the type summary: ragweed pollen reads 13 (Low) today. The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

How to read this: the “ragweed” figure on this site is the modelled weed pollen index — the weed group (ragweed + mugwort) — printed under the ragweed name the rankings use.

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’s readings.

What this ragweed pollen level means

Low risk. Keep windows open; consider allergy meds only if sensitive.

Enjoy outdoor activities.

The guides name no separate weed chapter for Hawaii — the year is carried by grasses, tree waves and wet-season mold. This month sits inside the ragweed pollen window for the Hawaii pattern, so today’s ragweed pollen reading should be judged against that chapter of the Hawaii year. The Hawaii allergy season guide singles out kiawe, flowering most heavily in late winter and spring, and grasses that pollinate in nearly every month.
