Pollen count Grundarhverfi residents check each morning
The Grundarhverfi pollen count today is 49 (Moderate). No single plant stands out in today’s readings; the Grass category is the one the index is led by. The full split is tree pollen 0.6, grass pollen 49, 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 Monday, November 9, 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 Grundarhverfi 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.
Outside its main late-spring and early-summer window, grass pollen usually appears as a small background value rather than the driver of the total. A low grass reading alongside a higher weed or mold value is a typical off-peak pattern. Grass should be read from its own value on this page, not assumed from the calendar: the index reports today’s modelled value, and the modelled value outranks any general seasonal expectation.

Pollen by type in Grundarhverfi
What is driving Grundarhverfi’s pollen today
The shape of today’s 49 (Moderate) is set by grass pollen at 49 (Moderate on its own scale) — about 77% of the four category readings added together, 35 points clear of the next category, weed pollen at 14. Grass-led totals tend to hold a level for days at a time rather than spike and clear, because grasses pollinate over an extended period. Grass pollen leading in November runs against the usual calendar — the Iceland grass chapter runs June to July — 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 Grundarhverfi, 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 20 to 49, changing band 1 time. Today’s 49 sits 9 points above the window’s average of 40.2 — a wide-open window, in which the day matters more than the average.

Grundarhverfi pollen through the year
The Grundarhverfi pollen year runs in chapters, set by the Nordic & Baltic North pattern and the Iceland 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 Iceland allergy season guide is published yet, so this page does not single out signature pollens for Grundarhverfi — 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 Iceland 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 Iceland year, April to September — a compressed season, which is why its chapters arrive in quick succession. No Iceland allergy season guide is published yet — this calendar follows the Nordic & Baltic North regional pattern. See Grundarhverfi pollen count rankings and Grundarhverfi on the pollen heatmap.
How to read this index
Pollen Atlas reports the Grundarhverfi 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 whatever the month. 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.
