Pollen count Thieu residents check each morning
The Thieu pollen count today is 36 (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 14 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 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 weed pollen or mold, reading noticeably higher than the rest, which is why the split is printed on every Thieu 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.
To see whether today’s pollen level holds, check the 5-day Thieu pollen forecast below — it is currently mixed, with Sunday the highest day in the window.
This is the pollen count Thieu residents check each morning, built from the day’s tree, grass, weed and mold readings.

Thieu allergies today
Thieu allergies today are set by the same reading as the pollen count above: the Total Pollen Index is 36 (Low), driven mainly by Ragweed. When people ask about Thieu allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Thieu.
Allergies in Thieu follow the Belgium 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 Thieu 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 Thieu allergy forecast: today reads 36 (Low), and the day-by-day outlook shows whether Thieu 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 Thieu today records is this same combined reading — tree, grass, weed and mold in one index.
The Thieu allergy count today is 36 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Thieu
What is driving Thieu’s pollen today
The shape of today’s 36 (Low) is set by weed pollen at 45 (Moderate on its own scale) — about 76% of the four category readings added together, 31 points clear of the next category, tree pollen at 14. 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 Belgium 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 Thieu, 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 35 to 39, never changing band. Today’s 36 sits 1 point below the window’s average of 36.8 — a steady window, in which one day reads much like the next.
Plants affecting Thieu now
Detailed plant-by-plant readings for Thieu 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.

Thieu pollen through the year
Three chapters make the Belgium pollen year, and Thieu 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 Belgium allergy season guide is published yet, so this page does not single out signature pollens for Thieu — 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 Belgium 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 Belgium year, February to October — leaving a quiet gap of roughly 3 months in the depth of the off-season. No Belgium allergy season guide is published yet — this calendar follows the Continental West regional pattern. See Thieu pollen count rankings and Thieu on the pollen heatmap.
How to read this index
Pollen Atlas reports the Thieu 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 Thieu, Belgium 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.
Thieu in today’s national picture
At 36 (Low), Thieu ranks joint 6835th of the 90896 cities Pollen Atlas tracks today — in the middle of the national table.

The whole table spans 48 points today — a wide-open day, when the top and bottom of the table are effectively in different seasons.

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Thieu resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Thieu, Belgium 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.
