Pollen count Groix residents check each morning

The Groix pollen count today is 25 (Low). The main driver is Ragweed, with weed pollen at 28 today. Tree pollen is the highest single category in the split at 28 (Low), ahead of weed pollen at 28 and grass pollen at 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 Friday, November 6, 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 Groix 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.

This is the pollen count Groix residents check each morning, built from the day’s tree, grass, weed and mold readings.

Groix allergies today

Groix allergies today are set by the same reading as the pollen count above: the Total Pollen Index is 25 (Low), driven mainly by Ragweed. When people ask about Groix allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Groix.

Allergies in Groix follow the France calendar set out below — the chapters, the plants behind them, and the 5-day forecast on this page show whether today is typical for the season or an exception to it. If you are checking allergies today in Groix before heading outdoors, the split at the top of this page is the part to read: it shows which pollen is doing the work today, not just how high the total sits.

Read the five-day table on this page as the Groix allergy forecast: today reads 25 (Low), and the day-by-day outlook shows whether Groix allergies are set to ease or build across the week — the days to plan outdoor time around are the ones where the index steps down, not just today.

In practice, the allergy count Groix today records is this same combined reading — tree, grass, weed and mold in one index.

The Groix allergy count today is 25 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Groix

What is driving Groix’s pollen today

The shape of today’s 25 (Low) is set by tree pollen at 28 (Low on its own scale) — about 49% of the four category readings added together, level with weed pollen at 28. 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 Groix, 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 24 to 26, never changing band. Today’s 25 sits 0 points below the window’s average of 25.4 — a steady window, in which one day reads much like the next.

Plants affecting Groix now

Detailed plant-by-plant readings for Groix 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.

Groix pollen through the year

The Groix 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 Groix — 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 Groix pollen count rankings and Groix on the pollen heatmap.

How to read this index

Pollen Atlas reports the Groix 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 Groix, 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.
