Pollen count São Paulo residents check each morning
The São Paulo pollen count today is 15 (Low). 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 8, grass pollen 16, weed pollen 12. Plant-by-plant detail for São Paulo, Brazil follows, along with the outlook for the days ahead. 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 São Paulo page.
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 São Paulo
What is driving São Paulo’s pollen today
The shape of today’s 15 (Low) is set by grass pollen at 16 (Low on its own scale) — about 44% of the four category readings added together, 4 points clear of the next category, weed pollen at 12. 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 São Paulo, 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 14 to 32, never changing band. Today’s 15 sits 6 points below the window’s average of 21 — a moving window, worth reading day by day rather than from the average.

November in São Paulo 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 São Paulo 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.
