Pollen count Maarssen residents check each morning

The Maarssen pollen count today is 32 (Low). The main driver is Ragweed, with weed pollen at 41 today. That total sits on a narrow base: weed pollen is 41 while tree pollen is just 7 and grass pollen 0.6. Plant-by-plant detail for Maarssen, Netherlands follows, along with the outlook for the days ahead. 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 Maarssen 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 Maarssen

What is driving Maarssen’s pollen today

The shape of today’s 32 (Low) is set by weed pollen at 41 (Moderate on its own scale) — about 84% of the four category readings added together, 34 points clear of the next category, tree pollen at 7. 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 Maarssen, 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 15 to 32, never changing band. Today’s 32 sits 6 points above the window’s average of 26.4 — a moving window, worth reading day by day rather than from the average.

Plants affecting Maarssen now

Detailed plant-by-plant readings for Maarssen 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.

Grass pollen is one of the categories with a non-zero reading today, at 0.6 (Low).

Maarssen pollen through the year

Chapter by chapter, the Maarssen 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 Maarssen — 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 Maarssen pollen count rankings and Maarssen on the pollen heatmap.

How to read this index

Pollen Atlas reports the Maarssen 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 Maarssen, 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.
