Pollen count Strongsville residents check each morning
The Strongsville pollen count today is 21 (Low). The main driver is Ragweed, with weed pollen at 27 today. Weed pollen leads the split at 27 (Low on its own scale), followed by tree pollen at 0.6 and grass 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 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 Strongsville 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 Strongsville
What is driving Strongsville’s pollen today
The shape of today’s 21 (Low) is set by weed pollen at 27 (Low on its own scale) — about 96% of the four category readings added together, 26.4 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 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 Strongsville, 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 21, never changing band. Today’s 21 sits 1 point above the window’s average of 20.4 — a steady window, in which one day reads much like the next.

Strongsville pollen through the year
Three chapters make the Ohio pollen year, and Strongsville 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.
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. The Ohio guide singles out ragweed, the state’s fall heavyweight, over a three-act year.
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 Strongsville 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 Strongsville, 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.
