Pollen count Sidlow residents check each morning
The Sidlow pollen count today is 28 (Low). No single plant stands out in today’s readings; the Tree category is the one the index is led by. The full split is tree pollen 28, grass pollen 0.6, weed pollen 9. Below, the plant detail and the multi-day outlook show whether today is the pattern or the exception. Pollen Atlas updated this count on Monday, November 9, 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 tree pollen, reading noticeably higher than the rest, which is why the split is printed on every Sidlow page.
Today’s reading for this city is quiet across the board, and a quiet day is best understood comparatively: the split shows no category carrying the total, and the plant section shows nothing reading high. Seasonal expectations set the background — which pollen types are common in this region at this time of year — but they never override the modelled value. This page reports the modelled reading first, and uses seasonal context only to explain the shape of the numbers it has already shown.

Pollen by type in Sidlow
What is driving Sidlow’s pollen today
The shape of today’s 28 (Low) is set by tree pollen at 28 (Low on its own scale) — about 74% of the four category readings added together, 19 points clear of the next category, weed pollen at 9. Tree readings are the fastest-moving of the four in their season, because species pollinate in sequence — a tree-led total can change character within a week. Tree pollen leading in November runs against the usual calendar — the United Kingdom tree chapter runs February to May — 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 Sidlow, 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 12 to 28, never changing band. Today’s 28 sits 7 points above the window’s average of 21.4 — a moving window, worth reading day by day rather than from the average.

Sidlow pollen through the year
Three chapters make the United Kingdom pollen year, and Sidlow follows them in the Atlantic West order. The tree chapter: 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. The grass chapter: grasses hold from late May into July, peaking in late spring and early summer. The weed chapter: 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 Sidlow — 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 Sidlow pollen count rankings and Sidlow on the pollen heatmap.
How to read this index
Pollen Atlas reports the Sidlow 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.
