Pollen count São Luis residents check each morning

The São Luis pollen count today is 43 (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 53, grass pollen 2, weed pollen 19. 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 São Luis 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.

This is the pollen count São Luis residents check each morning, built from the day’s tree, grass, weed and mold readings.

Pollen by type in São Luis

What is driving São Luis’s pollen today

The shape of today’s 43 (Moderate) is set by tree pollen at 53 (Moderate on its own scale) — about 72% of the four category readings added together, 34 points clear of the next category, weed pollen at 19. 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 Luis, 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 43, changing band 1 time. Today’s 43 sits 20 points above the window’s average of 23.4 — a wide-open window, in which the day matters more than the average.

São Luis pollen through the year

The São Luis 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 São Luis — 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 Luis 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 Luis pollen count rankings and São Luis on the pollen heatmap.

How to read this index

Pollen Atlas reports the São Luis 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.
