Pollen count Santiago do Cacém residents check each morning
The Santiago do Cacém pollen count today is 47 (Moderate). 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 58, grass pollen 2, weed pollen 21. 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 Saturday, November 7, 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 Santiago do Cacém 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.
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 Santiago do Cacém
What is driving Santiago do Cacém’s pollen today
The shape of today’s 47 (Moderate) is set by tree pollen at 58 (Moderate on its own scale) — about 72% of the four category readings added together, 37 points clear of the next category, weed pollen at 21. 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 Santiago do Cacém, 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 17 to 47, changing band 1 time. Today’s 47 sits 23 points above the window’s average of 24.2 — a wide-open window, in which the day matters more than the average.

Santiago do Cacém pollen through the year
The Santiago do Cacém pollen year runs in chapters, set by the Mediterranean pattern and the Portugal calendar. Trees come first: cypress opens the year in winter, hazel and alder follow early, and olive carries the spring peak from April into May. Grasses take the middle of the year: grasses build from spring and peak from April into June, earlier in the south. Weeds close it out: 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 Santiago do Cacém — the calendar above is the Mediterranean regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Santiago do Cacém 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 Santiago do Cacém pollen count rankings and Santiago do Cacém on the pollen heatmap.
How to read this index
Pollen Atlas reports the Santiago do Cacém 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.
