Pollen count Nollen residents check each morning
The Nollen pollen count today is 39 (Low). The main driver is Ragweed, with weed pollen at 49 today. That total sits on a narrow base: weed pollen is 49 while tree pollen is just 10 and grass pollen 0.6. Plant-by-plant detail for Nollen, Netherlands follows, along with the outlook for the days ahead. 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 Nollen 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 Nollen residents check each morning, built from the day’s tree, grass, weed and mold readings.

When people ask about Nollen allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Nollen.
Allergies in Nollen follow the Netherlands 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 Nollen 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 Nollen allergy forecast: today reads 39 (Low), and the day-by-day outlook shows whether Nollen 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 Nollen today records is this same combined reading — tree, grass, weed and mold in one index.
The Nollen allergy count today is 39 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Nollen
What is driving Nollen’s pollen today
The shape of today’s 39 (Low) is set by weed pollen at 49 (Moderate on its own scale) — about 82% of the four category readings added together, 39 points clear of the next category, tree pollen at 10. 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 Nollen, 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 34 to 39, never changing band. Today’s 39 sits 2 points above the window’s average of 36.8 — a steady window, in which one day reads much like the next.
Plants affecting Nollen now
Detailed plant-by-plant readings for Nollen 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.
Tree pollen is one of the categories with a non-zero reading today, at 10 (Low).
Grass pollen is one of the categories with a non-zero reading today, at 0.6 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 49 (Moderate).
In the Atlantic West pattern, the plants that typically shape this city’s year are early hazel and alder, a spring birch and oak wave, late-spring and summer grasses, and a modest late-summer weed finish — named here as regional context only, not as today\u2019s measurements.

Nollen pollen through the year
Chapter by chapter, the Nollen pollen year runs like this:
- 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.
- Grasses hold from late May into July, peaking in late spring and early summer.
- 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 Nollen — 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 Nollen pollen count rankings and Nollen on the pollen heatmap.
How to read this index
Pollen Atlas reports the Nollen 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 Nollen, 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.
Nollen in today’s national picture
At 39 (Low), Nollen ranks joint 3489th 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 Nollen resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Nollen, Netherlands 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.
