Pollen count De Haan residents check each morning
The De Haan pollen count today is 19 (Low). The main driver is Ragweed, with weed pollen at 23 today. The full split is tree pollen 12, grass pollen 0.6, weed pollen 23. 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 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 De Haan 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 De Haan
What is driving De Haan’s pollen today
The shape of today’s 19 (Low) is set by weed pollen at 23 (Low on its own scale) — about 65% of the four category readings added together, 11 points clear of the next category, tree pollen at 12. 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 De Haan, 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 19 to 44, changing band 2 times. Today’s 19 sits 14 points below the window’s average of 33.4 — a wide-open window, in which the day matters more than the average.

De Haan pollen through the year
The De Haan pollen year runs in chapters, set by the Continental West pattern and the Belgium 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 Belgium allergy season guide is published yet, so this page does not single out signature pollens for De Haan — 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 De Haan pollen count rankings and De Haan on the pollen heatmap.
How to read this index
Pollen Atlas reports the De Haan 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 De Haan, 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.
