Pollen count Arroyo zona urbana residents check each morning
The Arroyo zona urbana pollen count today is 9 (Low). The main driver is Ragweed, with weed pollen at 9 today. The full split is tree pollen 8, grass pollen 8, weed pollen 9. 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 weed pollen or mold, reading noticeably higher than the rest, which is why the split is printed on every Arroyo zona urbana 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 Arroyo zona urbana
What is driving Arroyo zona urbana’s pollen today
The shape of today’s 9 (Low) is set by weed pollen at 9 (Low on its own scale) — about 36% of the four category readings added together, 1 points clear of the next category, tree pollen at 8. 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 PR calendar working as expected — November falls in the closing weeks of the state’s weed chapter.
Plant-level detail is not in today’s feed for Arroyo zona urbana, 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 9 to 19, never changing band. Today’s 9 sits 4 points below the window’s average of 12.6 — a moving window, worth reading day by day rather than from the average.

Arroyo zona urbana pollen through the year
The Arroyo zona urbana pollen year runs in chapters, set by the Southeast pattern and the PR calendar. Trees come first: trees can start as early as February and peak in April. Grasses take the middle of the year: grasses follow in May and run through the summer. Weeds close it out: ragweed runs from mid-August to the first frost. Mold is the quiet fourth player, sustained by river-valley humidity between the pollen waves.

November in Arroyo zona urbana sits inside the weed chapter of the PR year, in its closing weeks — the part of the calendar today’s readings should be judged against. Between them, the three chapters cover 10 months of the PR year, February to November — a long season by national standards, with only a short quiet gap. No PR allergy season guide is published yet — this calendar follows the Southeast regional pattern. See Arroyo zona urbana pollen count rankings and Arroyo zona urbana on the pollen heatmap.
How to read this index
Pollen Atlas reports the Arroyo zona urbana 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 Arroyo zona urbana, PR 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.
