Pollen count Mount Stewart residents check each morning
The Mount Stewart pollen count today is 19 (Low). No single plant stands out in today’s readings; the Grass category is the one the index is led by. Weed pollen is the highest single category in the split at 19 (Low), ahead of grass pollen at 12 and tree pollen at 0.6. 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 Friday, November 13, 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 Mount Stewart page.
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 Mount Stewart
What is driving Mount Stewart’s pollen today
The shape of today’s 19 (Low) is set by weed pollen at 19 (Low on its own scale) — about 60% of the four category readings added together, 7 points clear of the next category, grass pollen at 12. 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 is the Prince Edward Island calendar working as expected — November falls in the closing weeks of the province’s weed chapter.
Plant-level detail is not in today’s feed for Mount Stewart, 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 18 to 19, never changing band. Today’s 19 sits 0 points above the window’s average of 18.8 — a steady window, in which one day reads much like the next.

Mount Stewart pollen through the year
The Mount Stewart pollen year runs in chapters, set by the Southeast pattern and the Prince Edward Island calendar. Trees come first: trees can start as early as February and peak in April. Grasses take the middle of the year: grasses follow in May and run through the summer. Weeds close it out: ragweed runs from mid-August to the first frost. Mold is the quiet fourth player, sustained by river-valley humidity between the pollen waves.
No Prince Edward Island allergy season guide is published yet, so this page does not single out signature pollens for Mount Stewart — the calendar above is the Southeast regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Mount Stewart sits inside the weed chapter of the Prince Edward Island year, in its closing weeks — the part of the calendar today’s readings should be judged against. Between them, the three chapters cover 10 months of the Prince Edward Island year, February to November — a long season by national standards, with only a short quiet gap. No Prince Edward Island allergy season guide is published yet — this calendar follows the Southeast regional pattern. See Mount Stewart pollen count rankings and Mount Stewart on the pollen heatmap.
How to read this index
Pollen Atlas reports the Mount Stewart 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.
