Pollen count Louisville residents check each morning
The Louisville pollen count today is 23 (Low). The main driver is Ragweed, with weed pollen at 30 today. The full split is tree pollen 0.6, grass pollen 1, weed pollen 30. 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 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 weed pollen or mold, reading noticeably higher than the rest, which is why the split is printed on every Louisville 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 Louisville
What is driving Louisville’s pollen today
The shape of today’s 23 (Low) is set by weed pollen at 30 (Low on its own scale) — about 95% of the four category readings added together, 29 points clear of the next category, grass pollen at 1. 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 Nebraska 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 Louisville, so the drivers have to be read from the category split above. The Nebraska guide’s account of Nebraska names cottonwood along the rivers, tallgrass at prairie scale, and ragweed as the main event — 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 23 to 23, never changing band. Today’s 23 sits level with the window’s average of 23 — a steady window, in which one day reads much like the next.
Plants affecting Louisville now
Detailed plant-by-plant readings for Louisville 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.

Grass pollen is one of the categories with a non-zero reading today, at 1 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 30 (Low).
In the South-Central Plains pattern, the plants that typically shape this city’s year are spring trees, prairie grasses and late-summer ragweed — named here as regional context only, not as today\u2019s measurements.

Louisville pollen through the year
The Louisville pollen year runs in chapters, set by the South-Central Plains pattern and the Nebraska 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 Nebraska allergy season guide names cottonwood along the rivers, tallgrass at prairie scale, and ragweed as the main event. Plains wind redistributes Nebraska pollen across counties within the day, so a light local cast can still produce serious regional days. Grass takes over from late May and holds the summer, on native tallgrass prairie, pasture and hay meadow at a scale no lawn state matches.
November falls between the main chapters of the Nebraska 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 Nebraska 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 Nebraska allergy season guide.
How to read this index
Pollen Atlas reports the Louisville 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 Louisville, NE 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.
