Pollen count Saulx-les-Chartreux residents check each morning
The Saulx-les-Chartreux pollen count today is 39 (Low). The main driver is Ragweed, with weed pollen at 45 today. Weed pollen leads the split at 45 (Moderate on its own scale), followed by tree pollen at 36 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 Saulx-les-Chartreux 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 Saulx-les-Chartreux
What is driving Saulx-les-Chartreux’s pollen today
The shape of today’s 39 (Low) is set by weed pollen at 45 (Moderate on its own scale) — about 55% of the four category readings added together, 9 points clear of the next category, tree pollen at 36. 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 France 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 Saulx-les-Chartreux, 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 25 to 39, changing band 1 time. Today’s 39 sits 5 points above the window’s average of 33.6 — a moving window, worth reading day by day rather than from the average.

Saulx-les-Chartreux pollen through the year
Three chapters make the France pollen year, and Saulx-les-Chartreux 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 France allergy season guide is published yet, so this page does not single out signature pollens for Saulx-les-Chartreux — 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 France 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 France year, February to October — leaving a quiet gap of roughly 3 months in the depth of the off-season. No France allergy season guide is published yet — this calendar follows the Continental West regional pattern.

How to read this index
Pollen Atlas reports the Saulx-les-Chartreux 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 Saulx-les-Chartreux, France 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.
