Pollen count Cape Breton residents check each morning

The Cape Breton pollen count today is 12 (Low). The main driver is Ragweed, with weed pollen at 14 today. Weed pollen leads the split at 14 (Low on its own scale), followed by grass pollen at 9 and tree pollen at 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 Friday, November 6, 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 Cape Breton page.

Fall is ragweed season across most of North America: 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. In the Northeast, autumn weed pollen typically winds down as colder nights arrive, so late-season totals can change quickly from week to week.

Cape Breton allergies today

Cape Breton allergies today are set by the same reading as the pollen count above: the Total Pollen Index is 12 (Low), driven mainly by Ragweed. When people ask about Cape Breton allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Cape Breton.

Allergies in Cape Breton follow the Nova Scotia calendar set out below — the chapters, the plants behind them, and the 5-day forecast on this page show whether today is typical for the season or an exception to it. If you are checking allergies today in Cape Breton before heading outdoors, the split at the top of this page is the part to read: it shows which pollen is doing the work today, not just how high the total sits.

Read the five-day table on this page as the Cape Breton allergy forecast: today reads 12 (Low), and the day-by-day outlook shows whether Cape Breton allergies are set to ease or build across the week — the days to plan outdoor time around are the ones where the index steps down, not just today.

In practice, the allergy count Cape Breton today records is this same combined reading — tree, grass, weed and mold in one index.

The Cape Breton allergy count today is 12 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Cape Breton

What is driving Cape Breton’s pollen today

The shape of today’s 12 (Low) is set by weed pollen at 14 (Low on its own scale) — about 59% of the four category readings added together, 5 points clear of the next category, grass pollen at 9. 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 runs against the usual calendar — the Nova Scotia weed chapter runs August to October — 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 Cape Breton, 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 18, never changing band. Today’s 12 sits 2 points below the window’s average of 13.6 — a moving window, worth reading day by day rather than from the average.

Plants affecting Cape Breton now

Detailed plant-by-plant readings for Cape Breton were not returned in today\u2019s source data, so this section summarises the pollen types the index above is built from instead of listing individual plants.

Cape Breton pollen through the year

Three chapters make the Nova Scotia pollen year, and Cape Breton follows them in the Northeast order. The tree chapter: trees open in late March and build to an oak-led peak in May. The grass chapter: grasses hold from late May into July. The weed chapter: ragweed builds from mid-August, peaks in September, and is ended by the first hard frost. Mold tracks the region’s humidity rather than a flowering calendar, and it fills the gaps between chapters.

No Nova Scotia allergy season guide is published yet, so this page does not single out signature pollens for Cape Breton — the calendar above is the Northeast regional pattern, and the plant detail on this page names what today’s feed actually records.

November falls between the main chapters of the Nova Scotia 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 Nova Scotia year, March to October — a compressed season, which is why its chapters arrive in quick succession. No Nova Scotia allergy season guide is published yet — this calendar follows the Northeast regional pattern. See Cape Breton pollen count rankings and Cape Breton on the pollen heatmap.

How to read this index

Pollen Atlas reports the Cape Breton 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 Cape Breton, NS 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.

Cape Breton in today’s US & Canada picture

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Cape Breton resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Cape Breton, NS can test whether tree, grass, weed or mold is the category that matters for you — the four readings at the top of this page are the starting point for that conversation.
