Pollen count St. Robert residents check each morning
The St. Robert pollen count today is 15 (Low). The main driver is Ragweed, with weed pollen at 19 today. The full split is tree pollen 0.6, grass pollen 2, weed pollen 19. 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 St. Robert 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. In the Plains and around the Great Lakes, ragweed is a familiar late-season plant of open ground, field edges and disturbed soil, which is why it so often leads inland autumn readings.

Pollen by type in St. Robert
What is driving St. Robert’s pollen today
The shape of today’s 15 (Low) is set by weed pollen at 19 (Low on its own scale) — about 88% of the four category readings added together, 17 points clear of the next category, grass pollen at 2. 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 Missouri 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 St. Robert, so the drivers have to be read from the category split above. The Missouri guide’s account of Missouri names oak and hickory over an elm and maple opening, in a season written by the state’s rivers — 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 13 to 15, never changing band. Today’s 15 sits 1 point above the window’s average of 13.8 — a steady window, in which one day reads much like the next.

St. Robert pollen through the year
The St. Robert pollen year runs in chapters, set by the South-Central Plains pattern and the Missouri calendar. Trees come first: river-corridor trees open from February — elm and maple first, then oak and hickory. Grasses take the middle of the year: prairie grasses take over in late May and hold the summer. Weeds close it out: ragweed builds from mid-August to the first hard frost, carried county to county by plains wind. Mold shares the long middle of the year, fed by river-bottom humidity.
The Missouri allergy season guide names oak and hickory over an elm and maple opening, in a season written by the state’s rivers. Missouri’s rivers write its season: the bottoms grow the weeds, plains winds move the grass, and oak-and-hickory highlands frame the map. The Bootheel runs on a Memphis schedule rather than a Kansas City one: springs start earlier there, and its ragweed season can outlast the rest of the state’s by weeks.
November falls between the main chapters of the Missouri 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 Missouri year, February to October — leaving a quiet gap of roughly 3 months in the depth of the off-season. The full calendar is set out in the Missouri allergy season guide.
How to read this index
Pollen Atlas reports the St. Robert 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 St. Robert, MO 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.
