Pollen count Onamia residents check each morning

The Onamia pollen count today is 20 (Low). The main driver is Ragweed, with weed pollen at 26 today. The full split is tree pollen 0.6, grass pollen 0.6, weed pollen 26. The sections below break that headline number down by plant, by day and by what the band means in practice. 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 Onamia 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.

When people ask about Onamia allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Onamia.

Allergies in Onamia follow the Minnesota calendar set out below — the chapters, the plants behind them, and the 5-day forecast on this page show whether today is typical for the season or an exception to it. If you are checking allergies today in Onamia before heading outdoors, the split at the top of this page is the part to read: it shows which pollen is doing the work today, not just how high the total sits.

Read the five-day table on this page as the Onamia allergy forecast: today reads 20 (Low), and the day-by-day outlook shows whether Onamia allergies are set to ease or build across the week — the days to plan outdoor time around are the ones where the index steps down, not just today.

In practice, the allergy count Onamia today records is this same combined reading — tree, grass, weed and mold in one index.

The Onamia allergy count today is 20 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Onamia

What is driving Onamia’s pollen today

The shape of today’s 20 (Low) is set by weed pollen at 26 (Low on its own scale) — about 96% of the four category readings added together, 25.4 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 Onamia, 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 20, never changing band. Today’s 20 sits 8 points above the window’s average of 12.2 — a moving window, worth reading day by day rather than from the average.

Plants affecting Onamia now

Detailed plant-by-plant readings for Onamia 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.

Onamia pollen through the year

The Onamia pollen year runs in chapters, set by the Midwest & Great Lakes pattern and the Minnesota calendar. Trees come first: trees run from March into May, later near the big lakes. Grasses take the middle of the year: grasses hold from May through July. Weeds close it out: 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 Onamia 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 Onamia, 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.

Onamia in today’s national picture
