Pollen count Castelnau-Chalosse residents check each morning
The Castelnau-Chalosse pollen count today is 36 (Low). 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 36, grass pollen 0.6, weed pollen 7. 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 tree pollen, reading noticeably higher than the rest, which is why the split is printed on every Castelnau-Chalosse page.
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.

Pollen by type in Castelnau-Chalosse
What is driving Castelnau-Chalosse’s pollen today
The shape of today’s 36 (Low) is set by tree pollen at 36 (Low on its own scale) — about 83% of the four category readings added together, 29 points clear of the next category, weed pollen at 7. 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 France tree chapter runs February 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 Castelnau-Chalosse, 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 21 to 36, changing band 1 time. Today’s 36 sits 9 points above the window’s average of 27.2 — a moving window, worth reading day by day rather than from the average.

Castelnau-Chalosse pollen through the year
The Castelnau-Chalosse pollen year runs in chapters, set by the Continental West pattern and the France calendar. Trees come first: hazel and alder open from February, and birch leads the spring peak through April and into May. Grasses take the middle of the year: grasses hold from May through July, cresting in late May and June. Weeds close it out: 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 Castelnau-Chalosse — 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 Castelnau-Chalosse 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.
