Pollen count Castella residents check each morning
The Castella pollen count today is 41 (Moderate). The main driver is Ragweed, with weed pollen at 50 today. That total sits on a narrow base: weed pollen is 50 while tree pollen is just 26 and grass pollen 0.6. Plant-by-plant detail for Castella, France follows, along with the outlook for the days ahead. Pollen Atlas updated this count on Sunday, November 8, 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 Castella 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.
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 Castella
What is driving Castella’s pollen today
The shape of today’s 41 (Moderate) is set by weed pollen at 50 (Moderate on its own scale) — about 65% of the four category readings added together, 24 points clear of the next category, tree pollen at 26. 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 Castella, 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 29 to 41, changing band 3 times. Today’s 41 sits 5 points above the window’s average of 35.8 — a moving window, worth reading day by day rather than from the average.

Castella pollen through the year
Chapter by chapter, the Castella pollen year runs like this:
- Hazel and alder open from February, and birch leads the spring peak through April and into May.

- 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 Castella — 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. See Castella pollen count rankings and Castella on the pollen heatmap.
How to read this index
Pollen Atlas reports the Castella 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 Castella, 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.
