Pollen count Carlisle residents check each morning
The Carlisle pollen count today is 28 (Low). The main driver is Ragweed, with weed pollen at 36 today. That total sits on a narrow base: weed pollen is 36 while tree pollen is just 0.6 and grass pollen 2. Plant-by-plant detail for Carlisle, IN 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 Carlisle 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 Carlisle
What is driving Carlisle’s pollen today
The shape of today’s 28 (Low) is set by weed pollen at 36 (Low on its own scale) — about 93% of the four category readings added together, 34 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 Indiana 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 Carlisle, so the drivers have to be read from the category split above. The Indiana guide’s account of Indiana names ragweed above all — the state’s defining allergen — over a maple, elm and oak spring — 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 27 to 28, never changing band. Today’s 28 sits 0 points above the window’s average of 27.8 — a steady window, in which one day reads much like the next.
Plants affecting Carlisle now
Detailed plant-by-plant readings for Carlisle 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.

Carlisle pollen through the year
Chapter by chapter, the Carlisle pollen year runs like this:
- Trees run from March into May, later near the big lakes.
- Grasses hold from May through July.
- Ragweed builds from mid-August, peaks in September, and ends at the first frost.
- Mold builds through the humid summer and fills the gaps between chapters.
The Indiana allergy season guide names ragweed above all — the state’s defining allergen — over a maple, elm and oak spring. April, May and September are Indiana’s peak months: spring trees, then the tree–grass overlap, then the ragweed crest. The south starts two to three weeks ahead of the north: Evansville’s Ohio River valley warms earlier, keeps mold longer, and meets frost later than the Lake Michigan shore.
November falls between the main chapters of the Indiana 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 Indiana year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Indiana allergy season guide.
How to read this index
Pollen Atlas reports the Carlisle 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 Carlisle, IN 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.
