Pollen count Sinclair residents check each morning
The Sinclair pollen count today is 8 (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 0.6 and grass pollen 0.6. Plant-by-plant detail for Sinclair, WY 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 Sinclair 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 Sinclair
What is driving Sinclair’s pollen today
The shape of today’s 8 (Low) is set by weed pollen at 11 (Low on its own scale) — about 90% of the four category readings added together, 10.4 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 Wyoming 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 Sinclair, so the drivers have to be read from the category split above. The Wyoming guide’s account of Wyoming names sagebrush, the state’s signature allergen, flowering from August into October and peaking in September — 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 8, never changing band. Today’s 8 sits 2 points above the window’s average of 5.6 — a steady window, in which one day reads much like the next.
Plants affecting Sinclair now
Detailed plant-by-plant readings for Sinclair 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 0.6 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 11 (Low).
In the High Basins pattern, the plants that typically shape this city’s year are river-corridor cottonwood and juniper, brief-summer meadow grasses, and sagebrush flowering late — named here as regional context only, not as today\u2019s measurements.

Sinclair pollen through the year
Chapter by chapter, the Sinclair pollen year runs like this:
- Spring is a river-corridor season — cottonwood and juniper from March into May — because most of Wyoming’s trees grow where the water is.
- Meadow and hay grasses carry the brief summer, from June into August.
- Sagebrush flowers from August into October and peaks in September, and the first hard frost ends it.
The Wyoming allergy season guide names sagebrush, the state’s signature allergen, flowering from August into October and peaking in September. Spring is a river-corridor season — cottonwood and juniper from March into May — because most of Wyoming’s trees grow where the water is. Wind is a season-maker here: pollen routinely arrives from far beyond the local landscape, so a town’s bad day may be grown a basin away.
November falls between the main chapters of the Wyoming 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 Wyoming year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Wyoming allergy season guide.
How to read this index
Pollen Atlas reports the Sinclair 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 Sinclair, WY 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.
Sinclair in today’s national picture
