Pollen count Santo da Serra residents check each morning
The Santo da Serra pollen count today is 18 (Low). The main driver is Ragweed, with weed pollen at 11 today. Tree pollen is the highest single category in the split at 18 (Low), ahead of weed pollen at 11 and grass pollen at 5. 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 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 Santo da Serra 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 Santo da Serra
What is driving Santo da Serra’s pollen today
The shape of today’s 18 (Low) is set by tree pollen at 18 (Low on its own scale) — about 53% of the four category readings added together, 7 points clear of the next category, weed pollen at 11. 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 Santo da Serra, 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 6 to 18, never changing band. Today’s 18 sits 6 points above the window’s average of 11.8 — a moving window, worth reading day by day rather than from the average.

Santo da Serra pollen through the year
The Santo da Serra 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 Santo da Serra — the calendar above is the Mediterranean regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Santo da Serra 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 Santo da Serra pollen count rankings and Santo da Serra on the pollen heatmap.
How to read this index
Pollen Atlas reports the Santo da Serra 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 Santo da Serra, Portugal 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.
