Pollen count Alto Alegre residents check each morning
The Alto Alegre pollen count today is 44 (Moderate). No single plant stands out in today’s readings; the Grass category is the one the index is led by. The full split is tree pollen 14, grass pollen 44, weed pollen 40. 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 14, 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 Alto Alegre 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.
Outside its main late-spring and early-summer window, grass pollen usually appears as a small background value rather than the driver of the total. A low grass reading alongside a higher weed or mold value is a typical off-peak pattern. Grass should be read from its own value on this page, not assumed from the calendar: the index reports today’s modelled value, and the modelled value outranks any general seasonal expectation.

Pollen by type in Alto Alegre
What is driving Alto Alegre’s pollen today
The shape of today’s 44 (Moderate) is set by grass pollen at 44 (Moderate on its own scale) — about 45% of the four category readings added together, 4 points clear of the next category, weed pollen at 40. 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 a modelled reading, reported as modelled — no regional calendar is asserted for Brazil, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for Alto Alegre, 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 44 to 44, never changing band. Today’s 44 sits level with the window’s average of 44 — a steady window, in which one day reads much like the next.

Alto Alegre pollen through the year
Three chapters make the Brazil pollen year, and Alto Alegre follows them in the Global order. The tree chapter: tree pollen seasons vary with local climate and vegetation, so this page reports the measured readings first and treats any calendar as background only.

The weed chapter: weed pollen seasons vary with local climate and vegetation, and no regional calendar is asserted for this area.
No Brazil allergy season guide is published yet, so this page does not single out signature pollens for Alto Alegre — the calendar above is the Global regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Alto Alegre is reported from its modelled readings, not from a regional calendar — no regional calendar is asserted for Brazil, so the calendar alone explains little today, and the modelled split above carries the story.

How to read this index
Pollen Atlas reports the Alto Alegre 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 whatever the month. 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.
