Pollen count Stornoway residents check each morning

The Stornoway pollen count today is 21 (Low). The main driver is Ragweed, with weed pollen at 23 today. That total sits on a narrow base: weed pollen is 23 while tree pollen is just 5 and grass pollen 20. Plant-by-plant detail for Stornoway, United Kingdom 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 Stornoway 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 Stornoway

What is driving Stornoway’s pollen today

The shape of today’s 21 (Low) is set by weed pollen at 23 (Low on its own scale) — about 48% of the four category readings added together, 3 points clear of the next category, grass pollen at 20. 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 United Kingdom 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 Stornoway, 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 21 to 24, never changing band. Today’s 21 sits 2 points below the window’s average of 22.6 — a steady window, in which one day reads much like the next.

Plants affecting Stornoway now

Stornoway pollen through the year

Chapter by chapter, the Stornoway 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 United Kingdom allergy season guide is published yet, so this page does not single out signature pollens for Stornoway — 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 United Kingdom 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 United Kingdom year, February to October — leaving a quiet gap of roughly 3 months in the depth of the off-season. No United Kingdom allergy season guide is published yet — this calendar follows the Atlantic West regional pattern. See Stornoway pollen count rankings and Stornoway on the pollen heatmap.

How to read this index

Pollen Atlas reports the Stornoway 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 Stornoway, United Kingdom 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.
