Pollen count Troy residents check each morning
The Troy pollen count today is 10 (Low). The main driver is Ragweed, with weed pollen at 11 today. That total sits on a narrow base: weed pollen is 11 while tree pollen is just 9 and grass pollen 1. Plant-by-plant detail for Troy, SC 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 Troy 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.

Pollen by type in Troy
What is driving Troy’s pollen today
The shape of today’s 10 (Low) is set by weed pollen at 11 (Low on its own scale) — about 52% of the four category readings added together, 2 points clear of the next category, tree pollen at 9. 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 is the South Carolina calendar working as expected — November falls in the closing weeks of the state’s weed chapter.
Plant-level detail is not in today’s feed for Troy, so the drivers have to be read from the category split above. The South Carolina guide’s account of South Carolina names oak — the pine dust filming cars in the same weeks is a comparatively weak allergen — 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 10 to 14, never changing band. Today’s 10 sits 3 points below the window’s average of 12.6 — a steady window, in which one day reads much like the next.

Troy pollen through the year
Chapter by chapter, the Troy pollen year runs like this:
- Trees can start as early as February and peak in April.
- Grasses follow in May and run through the summer.
- Ragweed runs from mid-August to the first frost.
- Mold is the quiet fourth player, sustained by river-valley humidity between the pollen waves.
The South Carolina allergy season guide names oak — the pine dust filming cars in the same weeks is a comparatively weak allergen. South Carolina’s season opens in February in warm years and can still be going in November in the southern half of the state; Greenville ranked ninth in the AAFA’s 2025 Allergy Capitals report. Warm-season grasses such as Bermuda grass pollinate from late spring deep into summer, with mold layered over the humid middle of the year.
November in Troy sits inside the weed chapter of the South Carolina year, in its closing weeks — the part of the calendar today’s readings should be judged against. Between them, the three chapters cover 10 months of the South Carolina year, February to November — a long season by national standards, with only a short quiet gap. The full calendar is set out in the South Carolina allergy season guide.
How to read this index
Pollen Atlas reports the Troy 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 Troy, SC 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.

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Troy resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every ragweed season, allergists in Troy, SC can test whether tree, grass, weed or mold is the category that matters for you — the four readings at the top of this page are the starting point for that conversation.
