Pollen count São Caetano residents check each morning
The São Caetano pollen count today is 26 (Low). No single plant stands out in today’s readings; the Tree category is the one the index is led by. The full split is tree pollen 26, grass pollen 1, weed pollen 7. Plant-by-plant detail for São Caetano, Portugal follows, along with the outlook for the days ahead. Pollen Atlas updated this count on Monday, November 9, 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 tree pollen, reading noticeably higher than the rest, which is why the split is printed on every São Caetano page.
Today’s reading for this city is quiet across the board, and a quiet day is best understood comparatively: the split shows no category carrying the total, and the plant section shows nothing reading high. Seasonal expectations set the background — which pollen types are common in this region at this time of year — but they never override the modelled value. This page reports the modelled reading first, and uses seasonal context only to explain the shape of the numbers it has already shown.

Pollen by type in São Caetano
What is driving São Caetano’s pollen today
The shape of today’s 26 (Low) is set by tree pollen at 26 (Low on its own scale) — about 76% of the four category readings added together, 19 points clear of the next category, weed pollen at 7. Tree readings are the fastest-moving of the four in their season, because species pollinate in sequence — a tree-led total can change character within a week. Tree pollen leading in November runs against the usual calendar — the Portugal tree chapter runs January to May — so today’s lead is the model outranking the pattern, and this page reports the modelled reading first.
Plant-level detail is not in today’s feed for São Caetano, 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 22 to 33, never changing band. Today’s 26 sits 1 point below the window’s average of 27.2 — a moving window, worth reading day by day rather than from the average.

São Caetano pollen through the year
Chapter by chapter, the São Caetano pollen year runs like this:
- Cypress opens the year in winter, hazel and alder follow early, and olive carries the spring peak from April into May.
- Grasses build from spring and peak from April into June, earlier in the south.
- Weeds — pellitory through the warm months and ragweed in late summer where it has spread — close a long season that can run into November.
No Portugal allergy season guide is published yet, so this page does not single out signature pollens for São Caetano — the calendar above is the Mediterranean regional pattern, and the plant detail on this page names what today’s feed actually records.
November in São Caetano sits inside the weed chapter of the Portugal 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 Portugal year, January to November — a long season by national standards, with only a short quiet gap. No Portugal allergy season guide is published yet — this calendar follows the Mediterranean regional pattern. See São Caetano pollen count rankings and São Caetano on the pollen heatmap.
How to read this index
Pollen Atlas reports the São Caetano 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.
