Pollen count Oberlin residents check each morning
The Oberlin 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 1, 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 Oberlin 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.

Allergies in Oberlin follow the Ohio 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 Oberlin 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 Oberlin allergy forecast: today reads 20 (Low), and the day-by-day outlook shows whether Oberlin 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 Oberlin today records is this same combined reading — tree, grass, weed and mold in one index.
The Oberlin allergy count today is 20 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Oberlin
What is driving Oberlin’s pollen today
The shape of today’s 20 (Low) is set by weed pollen at 26 (Low on its own scale) — about 94% of the four category readings added together, 25 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 Ohio 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 Oberlin, so the drivers have to be read from the category split above. The Ohio guide’s account of Ohio names ragweed, the state’s fall heavyweight, over a three-act year — 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 20 to 28, never changing band. Today’s 20 sits 6 points below the window’s average of 26.2 — a moving window, worth reading day by day rather than from the average.
Plants affecting Oberlin now
Detailed plant-by-plant readings for Oberlin 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 26 (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.
Plant detail returns here automatically on any day the source data includes it.

Oberlin pollen through the year
The Oberlin pollen year runs in chapters, set by the Midwest & Great Lakes pattern and the Ohio 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 Ohio allergy season guide names ragweed, the state’s fall heavyweight, over a three-act year. Cleveland’s spring crest typically trails Cincinnati’s, a delay tied to cold Lake Erie water slowing the warm-up along the northern shore. The AAFA cites a striking figure for the fall act: a single ragweed plant can produce up to a billion grains of pollen in one season.
November falls between the main chapters of the Ohio 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 Ohio year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Ohio allergy season guide.
How to read this index
Pollen Atlas reports the Oberlin 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 Oberlin, OH 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.
Oberlin in today’s national picture
