Pollen count Johnstown Bridge residents check each morning

Plant-by-plant detail for Johnstown Bridge, Ireland follows, along with the outlook for the days ahead. 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 Johnstown Bridge 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 Johnstown Bridge
What is driving Johnstown Bridge’s pollen today
The shape of today’s 8 (Low) is set by tree pollen at 8 (Low on its own scale) — about 40% of the four category readings added together, 1 points clear of the next category, weed pollen at 7. 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 Ireland tree chapter runs February to May — so today’s lead is the model outranking the pattern, and this page reports the modelled reading first.
In the plant detail, Mugwort (weed) carries the strongest single plant reading, at a Universal Pollen Index of 1 (Very Low). No Ireland allergy season guide is published yet to cross-reference these names against — they are today’s measured plant detail for Johnstown Bridge, ranked by plant index.
Across the five-day window the Total Pollen Index runs from 7 to 8, never changing band. Today’s 8 sits 0 points above the window’s average of 7.6 — a steady window, in which one day reads much like the next.

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