Pollen count Roulaz residents check each morning
The Roulaz pollen count today is 18 (Low). No single plant stands out in today’s readings; the Grass category is the one the index is led by. The full split is tree pollen 0.6, grass pollen 18, weed pollen 0.6. 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 Sunday, November 8, 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 grass pollen, reading noticeably higher than the rest, which is why the split is printed on every Roulaz page.
Outside its main late-spring and early-summer window, grass pollen usually appears as a small background value rather than the driver of the total. A low grass reading alongside a higher weed or mold value is a typical off-peak pattern. Grass should be read from its own value on this page, not assumed from the calendar: the index reports today’s modelled value, and the modelled value outranks any general seasonal expectation.

Pollen by type in Roulaz
What is driving Roulaz’s pollen today
The shape of today’s 18 (Low) is set by grass pollen at 18 (Low on its own scale) — about 94% of the four category readings added together, 17.4 points clear of the next category, tree pollen at 0.6. Grass-led totals tend to hold a level for days at a time rather than spike and clear, because grasses pollinate over an extended period. Grass pollen leading in November runs against the usual calendar — the Italy grass chapter runs March to June — 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 Roulaz, 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 7 to 18, never changing band. Today’s 18 sits 5 points above the window’s average of 13.2 — a moving window, worth reading day by day rather than from the average.

Roulaz pollen through the year
The Roulaz pollen year runs in chapters, set by the Mediterranean pattern and the Italy 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 Italy allergy season guide is published yet, so this page does not single out signature pollens for Roulaz — the calendar above is the Mediterranean regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Roulaz sits inside the weed chapter of the Italy 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 Italy year, January to November — a long season by national standards, with only a short quiet gap. No Italy allergy season guide is published yet — this calendar follows the Mediterranean regional pattern. See Roulaz pollen count rankings and Roulaz on the pollen heatmap.
How to read this index
Pollen Atlas reports the Roulaz 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.
