Pollen count Apra Harbor residents check each morning
The Apra Harbor pollen count today is 34 (Moderate). The main driver is Ragweed, with weed pollen at 34 today. That total sits on a narrow base: weed pollen is 34 while tree pollen is just 10 and grass pollen 30. Plant-by-plant detail for Apra Harbor, Guam follows, along with the outlook for the days ahead. Pollen Atlas updated this count on Friday, November 13, 2026.
A Moderate band means the Total Pollen Index sits in the middle of the 0–100 scale — neither a quiet day nor a peak day. On moderate days the split usually explains the total: one or two categories do most of the work while the others stay low. The Apra Harbor split above shows exactly which categories those are today, and the forecast below shows whether the moderate reading is a plateau or a step toward a higher band.
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 Apra Harbor
What is driving Apra Harbor’s pollen today
The shape of today’s 34 (Moderate) is set by weed pollen at 34 (Moderate on its own scale) — about 46% of the four category readings added together, 4 points clear of the next category, grass pollen at 30. 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 a modelled reading, reported as modelled — no regional calendar is asserted for Guam, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for Apra Harbor, so the drivers have to be read from the category split above — it shows how much of today’s total each category is actually carrying, and plant detail returns here automatically on any day the feed includes it.
Across the five-day window the Total Pollen Index runs from 33 to 40, never changing band. Today’s 34 sits 1 point below the window’s average of 34.6 — a moving window, worth reading day by day rather than from the average.

How to read this index
Pollen Atlas reports the Apra Harbor 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 Apra Harbor, Guam 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.
