Pollen count Old Monroe residents check each morning
The Old Monroe pollen count today is 29 (Low). The main driver is Ragweed, with weed pollen at 37 today. That total sits on a narrow base: weed pollen is 37 while tree pollen is just 0.6 and grass pollen 2. Plant-by-plant detail for Old Monroe, MO follows, along with the outlook for the days ahead. 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 Old Monroe 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 Old Monroe
What is driving Old Monroe’s pollen today
The shape of today’s 29 (Low) is set by weed pollen at 37 (Low on its own scale) — about 93% of the four category readings added together, 35 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 Old Monroe, 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 28 to 29, never changing band. Today’s 29 sits 1 point above the window’s average of 28.4 — a steady window, in which one day reads much like the next.

Old Monroe pollen through the year
Chapter by chapter, the Old Monroe pollen year runs like this:
- River-corridor trees open from February — elm and maple first, then oak and hickory.
- Prairie grasses take over in late May and hold the summer.
- 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 Old Monroe 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 Old Monroe, 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.
