Pollen count South Haven residents check each morning
The South Haven pollen count today is 22 (Low). The main driver is Ragweed, with weed pollen at 29 today. That total sits on a narrow base: weed pollen is 29 while tree pollen is just 0.6 and grass pollen 0.6. Plant-by-plant detail for South Haven, MN 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 South Haven 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 South Haven
What is driving South Haven’s pollen today
The shape of today’s 22 (Low) is set by weed pollen at 29 (Low on its own scale) — about 96% of the four category readings added together, 28.4 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 Minnesota 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 South Haven, so the drivers have to be read from the category split above. The Minnesota guide’s account of Minnesota names birch, a signature northern spring pollen, and southern-Minnesota ragweed — 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 5 to 22, never changing band. Today’s 22 sits 10 points above the window’s average of 12 — a moving window, worth reading day by day rather than from the average.

South Haven pollen through the year
Chapter by chapter, the South Haven 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 Minnesota allergy season guide names birch, a signature northern spring pollen, and southern-Minnesota ragweed. Minnesota’s season is one of the shortest in the continental US: trees typically crest in May, and the Twin Cities start weeks after Chicago in most springs. Frost can end ragweed as early as late September in the north, while southern Minnesota sits in strong ragweed country.
November falls between the main chapters of the Minnesota 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 Minnesota year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Minnesota allergy season guide.
How to read this index
Pollen Atlas reports the South Haven 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 South Haven, MN 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.
