Pollen count Iron River residents check each morning
The Iron River pollen count today is 15 (Low). The main driver is Ragweed, with weed pollen at 20 today. That total sits on a narrow base: weed pollen is 20 while tree pollen is just 0.6 and grass pollen 0.6. Plant-by-plant detail for Iron River, MI 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 Iron River 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 Iron River
What is driving Iron River’s pollen today
The shape of today’s 15 (Low) is set by weed pollen at 20 (Low on its own scale) — about 94% of the four category readings added together, 19.4 points clear of the next category, tree pollen at 0.6. 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 Iron River, 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 6 to 15, never changing band. Today’s 15 sits 4 points above the window’s average of 11.4 — a moving window, worth reading day by day rather than from the average.
Plants affecting Iron River now
Detailed plant-by-plant readings for Iron River 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 0.6 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 20 (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.

Iron River pollen through the year
Chapter by chapter, the Iron River 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 Michigan allergy season guide names birch and oak in a compressed late-spring stack, and ragweed as the heavy fall finish. 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.
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 Iron River 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 Iron River, 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.
