Pollen count Kärna residents check each morning
The Kärna pollen count today is 49 (Moderate). The main driver is Ragweed, with weed pollen at 49 today. The full split is tree pollen 0.6, grass pollen 6, weed pollen 49. 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 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 Kärna 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 Kärna
What is driving Kärna’s pollen today
The shape of today’s 49 (Moderate) is set by weed pollen at 49 (Moderate on its own scale) — about 88% of the four category readings added together, 43 points clear of the next category, grass pollen at 6. 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 Kärna, 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 49, changing band 1 time. Today’s 49 sits 13 points above the window’s average of 35.8 — a wide-open window, in which the day matters more than the average.
Plants affecting Kärna now

Kärna pollen through the year
The Kärna 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 Kärna — 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 Kärna pollen count rankings and Kärna on the pollen heatmap.
How to read this index
Pollen Atlas reports the Kärna 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 Kärna, 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.
