Pollen count Lausanne residents check each morning

The Lausanne pollen count today is 22 (Low). The main driver is Ragweed, with weed pollen at 28 today. Weed pollen leads the split at 28 (Low on its own scale), followed by tree pollen at 3 and grass pollen at 0.6. 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 Lausanne 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 Lausanne

What is driving Lausanne’s pollen today

The shape of today’s 22 (Low) is set by weed pollen at 28 (Low on its own scale) — about 89% of the four category readings added together, 25 points clear of the next category, tree pollen at 3. 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 runs against the usual calendar — the Switzerland weed chapter runs August to October — 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 Lausanne, 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 14 to 30, never changing band. Today’s 22 sits 0 points below the window’s average of 22.2 — a moving window, worth reading day by day rather than from the average.

Plants affecting Lausanne now

Detailed plant-by-plant readings for Lausanne were not returned in today\u2019s source data, so this section summarises the pollen types the index above is built from instead of listing individual plants.

Lausanne pollen through the year

Three chapters make the Switzerland pollen year, and Lausanne follows them in the Continental West order. The tree chapter: hazel and alder open from February, and birch leads the spring peak through April and into May. The grass chapter: grasses hold from May through July, cresting in late May and June. The weed chapter: mugwort and ragweed build from August, peak in September, and are ended by the first hard frost. Mold builds through the humid summer and fills the gaps between chapters.

No Switzerland allergy season guide is published yet, so this page does not single out signature pollens for Lausanne — the calendar above is the Continental West regional pattern, and the plant detail on this page names what today’s feed actually records.

November falls between the main chapters of the Switzerland pollen year — the tail of one and the approach of the next — so the calendar alone explains little today, and the modelled split above carries the story. Between them, the three chapters cover 9 months of the Switzerland year, February to October — leaving a quiet gap of roughly 3 months in the depth of the off-season. No Switzerland allergy season guide is published yet — this calendar follows the Continental West regional pattern. See Lausanne pollen count rankings and Lausanne on the pollen heatmap.

How to read this index

Pollen Atlas reports the Lausanne 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 Lausanne, Switzerland 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.

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Lausanne resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Lausanne, Switzerland can test whether tree, grass, weed or mold is the category that matters for you — the four readings at the top of this page are the starting point for that conversation.
