Pollen count Calfven residents check each morning
The Calfven pollen count today is 41 (Moderate). The main driver is Ragweed, with weed pollen at 50 today. Weed pollen leads the split at 50 (Moderate on its own scale), followed by tree pollen at 21 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 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 Calfven 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 Calfven
What is driving Calfven’s pollen today
The shape of today’s 41 (Moderate) is set by weed pollen at 50 (Moderate on its own scale) — about 70% of the four category readings added together, 29 points clear of the next category, tree pollen at 21. 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 Netherlands 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 Calfven, 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 17 to 41, changing band 2 times. Today’s 41 sits 5 points above the window’s average of 36 — a moving window, worth reading day by day rather than from the average.

Calfven pollen through the year
Three chapters make the Netherlands pollen year, and Calfven follows them in the Atlantic West order. The tree chapter: hazel and alder can open as early as February in mild winters, and the main tree wave — birch, then oak — builds through spring to a May peak. The grass chapter: grasses hold from late May into July, peaking in late spring and early summer. The weed chapter: weeds are the minor closing act — mugwort through late summer, with ragweed localised and generally light this far west. Mold tracks the region’s Atlantic humidity rather than a flowering calendar, and it fills the gaps between chapters.
No Netherlands allergy season guide is published yet, so this page does not single out signature pollens for Calfven — the calendar above is the Atlantic 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 Netherlands 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 Netherlands year, February to October — leaving a quiet gap of roughly 3 months in the depth of the off-season. No Netherlands allergy season guide is published yet — this calendar follows the Atlantic West regional pattern. See Calfven pollen count rankings and Calfven on the pollen heatmap.
How to read this index
Pollen Atlas reports the Calfven 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 Calfven, Netherlands 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.
