Pollen count Coldwater residents check each morning
The Coldwater pollen count today is 22 (Low). The main driver is Ragweed, with weed pollen at 28 today. Weed pollen leads the split at 28 (Low on its own scale), followed by grass pollen at 1 and tree pollen at 0.6. Below, the plant detail and the multi-day outlook show whether today is the pattern or the exception. 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 Coldwater 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 Coldwater
What is driving Coldwater’s pollen today
The shape of today’s 22 (Low) is set by weed pollen at 28 (Low on its own scale) — about 95% of the four category readings added together, 27 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 Michigan 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 Coldwater, so the drivers have to be read from the category split above. The Michigan guide’s account of Michigan names birch and oak in a compressed late-spring stack, and ragweed as the heavy fall finish — 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 21 to 22, never changing band. Today’s 22 sits 1 point above the window’s average of 21.4 — a steady window, in which one day reads much like the next.
Plants affecting Coldwater now
Detailed plant-by-plant readings for Coldwater 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.
Tree pollen is one of the categories with a non-zero reading today, at 0.6 (Low).
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 28 (Low).
In the Midwest & Great Lakes pattern, the plants that typically shape this city’s year are spring trees, late-spring and summer grasses, and late-summer and autumn ragweed — named here as regional context only, not as today\u2019s measurements.

Coldwater pollen through the year
Three chapters make the Michigan pollen year, and Coldwater follows them in the Midwest & Great Lakes order. The tree chapter: trees run from March into May, later near the big lakes. The grass chapter: grasses hold from May through July. The weed chapter: 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.
Lake moderation delays Michigan’s spring, so birch and oak peaks arrive close together in late spring rather than spread across two months. The AAFA’s research consistently treats the Great Lakes and Ohio Valley as a high-burden region across tree, grass and weed scores. The Michigan guide singles out birch and oak in a compressed late-spring stack, and ragweed as the heavy fall finish.
November falls between the main chapters of the Michigan 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 Michigan year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Michigan allergy season guide.
How to read this index
Pollen Atlas reports the Coldwater 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 Coldwater, MI 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.
