Pollen count West Brule residents check each morning

The West Brule pollen count today is 21 (Low). The main driver is Ragweed, with weed pollen at 28 today. The full split is tree pollen 0.6, grass pollen 0.6, weed pollen 28. 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 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 West Brule 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 West Brule

What is driving West Brule’s pollen today

The shape of today’s 21 (Low) is set by weed pollen at 28 (Low on its own scale) — about 96% of the four category readings added together, 27.4 points clear of the next category, tree pollen at 0.6. 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 South Dakota 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 West Brule, so the drivers have to be read from the category split above. The South Dakota guide’s account of South Dakota names river-corridor cottonwood, elm and ash in spring, and a divided fall — ragweed in the east, sagebrush in the west — the pollens behind readings of this shape in this state — and the split shows how much of today’s total each category is actually carrying.

Across the five-day window the Total Pollen Index runs from 5 to 21, never changing band. Today’s 21 sits 8 points above the window’s average of 12.8 — a moving window, worth reading day by day rather than from the average.

Plants affecting West Brule now

West Brule pollen through the year

The West Brule pollen year runs in chapters, set by the Northern Plains pattern and the South Dakota calendar. Trees come first: river-corridor elm, cottonwood and ash open from March in South Dakota, while North Dakota’s trees flower in late spring, in May. Grasses take the middle of the year: grasses run from May into July, peaking in June and July. Weeds close it out: ragweed in the east and sagebrush in the west run from August until the first hard frost.

The South Dakota allergy season guide names river-corridor cottonwood, elm and ash in spring, and a divided fall — ragweed in the east, sagebrush in the west. The Missouri River splits the state into two regimes: a humid, farmed east where ragweed dominates the fall, and a dry, ranched west ruled by sagebrush, wormwood and Russian thistle. The Black Hills run their own cooler, higher calendar, while the southeastern corner around Sioux Falls starts earliest and finishes latest.

November falls between the main chapters of the South Dakota 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 South Dakota year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the South Dakota allergy season guide.

How to read this index

Pollen Atlas reports the West Brule 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 West Brule, SD 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.
