Pollen count Grundsund residents check each morning
The Grundsund pollen count today is 14 (Low). The main driver is Ragweed, with weed pollen at 14 today. The full split is tree pollen 0.6, grass pollen 10, weed pollen 14. 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 Sunday, November 8, 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 Grundsund 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 Grundsund
What is driving Grundsund’s pollen today
The shape of today’s 14 (Low) is set by weed pollen at 14 (Low on its own scale) — about 57% of the four category readings added together, 4 points clear of the next category, grass 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 Sweden weed chapter runs August to September — 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 Grundsund, 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 5 to 14, never changing band. Today’s 14 sits 5 points above the window’s average of 9 — a moving window, worth reading day by day rather than from the average.

Grundsund pollen through the year
The Grundsund pollen year runs in chapters, set by the Nordic & Baltic North pattern and the Sweden calendar. Trees come first: the season is compressed: alder stirs first, and birch — the region’s signature spring pollen — peaks through May into early June. Grasses take the middle of the year: grasses own a brief early-summer peak, cresting around the first hay cutting in June and July. Weeds close it out: mugwort runs through August, and ragweed is scarce at these latitudes — the late window is short and light. Mold rises late in the short season, from decaying vegetation as the brief summer closes.
No Sweden allergy season guide is published yet, so this page does not single out signature pollens for Grundsund — the calendar above is the Nordic & Baltic North regional pattern, and the plant detail on this page names what today’s feed actually records.
November falls between the main chapters of the Sweden 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 6 months of the Sweden year, April to September — a compressed season, which is why its chapters arrive in quick succession. No Sweden allergy season guide is published yet — this calendar follows the Nordic & Baltic North regional pattern. See Grundsund pollen count rankings and Grundsund on the pollen heatmap.
How to read this index
Pollen Atlas reports the Grundsund 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 Grundsund, Sweden 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.
