Pollen count Fort Riley residents check each morning
The Fort Riley pollen count today is 20 (Low). The main driver is Ragweed, with weed pollen at 26 today. That total sits on a narrow base: weed pollen is 26 while tree pollen is just 0.6 and grass pollen 2. Plant-by-plant detail for Fort Riley, KS follows, along with the outlook for the days ahead. 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 Fort Riley 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 Fort Riley
What is driving Fort Riley’s pollen today
The shape of today’s 20 (Low) is set by weed pollen at 26 (Low on its own scale) — about 91% of the four category readings added together, 24 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 Kansas 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 Fort Riley, so the drivers have to be read from the category split above. The Kansas guide’s account of Kansas names ragweed, intense from late summer to frost — 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 19 to 20, never changing band. Today’s 20 sits 0 points above the window’s average of 19.8 — a steady window, in which one day reads much like the next.

Fort Riley pollen through the year
Chapter by chapter, the Fort Riley 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 Kansas allergy season guide names ragweed, intense from late summer to frost. The AAFA’s 2025 Allergy Capitals report ranked Wichita No. 1, the most challenging US metro scored — and plains wind is the multiplier, so Kansas counts often rise and fall with regional wind patterns rather than local flowering alone. The EPA tracks ragweed season length as a climate indicator, and the central plains sit in the region where that season is naturally long.
November falls between the main chapters of the Kansas 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 Kansas 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 Kansas allergy season guide.
How to read this index
Pollen Atlas reports the Fort Riley 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 Fort Riley, KS 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.
