Pollen count Greater Sudbury residents check each morning
The Greater Sudbury pollen count today is 5 (Low). No single plant stands out in today’s readings; the Grass category is the one the index is led by. The full split is tree pollen 0.6, grass pollen 4, weed pollen 0.6. Below, the plant detail and the multi-day outlook show whether today is the pattern or the exception. 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 grass pollen, reading noticeably higher than the rest, which is why the split is printed on every Greater Sudbury 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 Greater Sudbury
What is driving Greater Sudbury’s pollen today
The shape of today’s 5 (Low) is set by grass pollen at 4 (Low on its own scale) — about 77% of the four category readings added together, 3.4 points clear of the next category, tree pollen at 0.6. Grass-led totals tend to hold a level for days at a time rather than spike and clear, because grasses pollinate over an extended period. Grass pollen leading in November runs against the usual calendar — the Ontario grass chapter runs May to July — 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 Greater Sudbury, 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 5 to 5, never changing band. Today’s 5 sits level with the window’s average of 5 — a steady window, in which one day reads much like the next.

Greater Sudbury pollen through the year
Three chapters make the Ontario pollen year, and Greater Sudbury follows them in the Midwest & Great Lakes order. The tree chapter: trees run from March into May, later near the big lakes. The grass chapter: grasses hold from May through July. The weed chapter: ragweed builds from mid-August, peaks in September, and ends at the first frost. Mold builds through the humid summer and fills the gaps between chapters.
No Ontario allergy season guide is published yet, so this page does not single out signature pollens for Greater Sudbury — the calendar above is the Midwest & Great Lakes regional pattern, and the plant detail on this page names what today’s feed actually records.
November falls between the main chapters of the Ontario 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 8 months of the Ontario year, March to October — a compressed season, which is why its chapters arrive in quick succession. No Ontario allergy season guide is published yet — this calendar follows the Midwest & Great Lakes regional pattern.

How to read this index
Pollen Atlas reports the Greater Sudbury 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.
