What is driving Henham’s pollen today

The shape of today’s 18 (Low) is set by tree pollen at 18 (Low on its own scale) — about 65% of the four category readings added together, 9 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 Henham, 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 7 to 19, never changing band. Today’s 18 sits 2 points above the window’s average of 15.8 — a moving window, worth reading day by day rather than from the average.

Henham pollen through the year

Three chapters make the United Kingdom pollen year, and Henham 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 Henham — 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 Henham pollen count rankings and Henham on the pollen heatmap.

How to read this index

Pollen Atlas reports the Henham 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.
