Pollen count Algés residents check each morning
The Algés pollen count today is 23 (Low). The main driver is Ragweed, with weed pollen at 26 today. Weed pollen leads the split at 26 (Low on its own scale), followed by tree pollen at 25 and grass pollen at 3. 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 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 weed pollen or mold, reading noticeably higher than the rest, which is why the split is printed on every Algés 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 Algés
What is driving Algés’s pollen today
The shape of today’s 23 (Low) is set by weed pollen at 26 (Low on its own scale) — about 48% of the four category readings added together, 1 points clear of the next category, tree pollen at 25. A weed-led total is the classic late-year shape: tree and grass pollen have usually receded, leaving weed pollen — and on damp days mold — to make up most of what the index records. Weed pollen leading in November is the Portugal calendar working as expected — November falls in the closing weeks of the country’s weed chapter.
Plant-level detail is not in today’s feed for Algés, 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 9 to 23, never changing band. Today’s 23 sits 11 points above the window’s average of 12.2 — a moving window, worth reading day by day rather than from the average.

Algés pollen through the year
Three chapters make the Portugal pollen year, and Algés follows them in the Mediterranean order. The tree chapter: cypress opens the year in winter, hazel and alder follow early, and olive carries the spring peak from April into May. The grass chapter: grasses build from spring and peak from April into June, earlier in the south. The weed chapter: 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 Algés — the calendar above is the Mediterranean regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Algés 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 Algés pollen count rankings and Algés on the pollen heatmap.
How to read this index
Pollen Atlas reports the Algés 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 Algés, 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.
Algés in today’s national picture
