Pollen count Swan Lake residents check each morning
The Swan Lake pollen count today is 15 (Low). No single plant stands out in today’s readings; the Grass category is the one the index is led by. The full split is tree pollen 0.6, grass pollen 19, weed pollen 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 grass pollen, reading noticeably higher than the rest, which is why the split is printed on every Swan Lake page.
Outside its main late-spring and early-summer window, grass pollen usually appears as a small background value rather than the driver of the total. A low grass reading alongside a higher weed or mold value is a typical off-peak pattern. Grass should be read from its own value on this page, not assumed from the calendar: the index reports today’s modelled value, and the modelled value outranks any general seasonal expectation.

Pollen by type in Swan Lake
What is driving Swan Lake’s pollen today
The shape of today’s 15 (Low) is set by grass pollen at 19 (Low on its own scale) — about 94% of the four category readings added together, 18.4 points clear of the next category, tree pollen at 0.6. Grass-led totals tend to hold a level for days at a time rather than spike and clear, because grasses pollinate over an extended period. Grass pollen leading in November runs against the usual calendar — the Montana grass chapter runs May to July — 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 Swan Lake, so the drivers have to be read from the category split above. The Montana guide’s account of Montana names sagebrush, flowering late on the dry benches, over a grass summer of timothy, orchard grass, bluegrass and ryegrass — 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 8 to 15, never changing band. Today’s 15 sits 4 points above the window’s average of 11.2 — a moving window, worth reading day by day rather than from the average.
Plants affecting Swan Lake now
Detailed plant-by-plant readings for Swan Lake 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 19 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 0.6 (Low).
In the Northern Rockies pattern, the plants that typically shape this city’s year are river-corridor trees, a June grass crest of timothy, orchard grass, bluegrass and ryegrass, and a late sagebrush finish — named here as regional context only, not as today\u2019s measurements.
Plant detail returns here automatically on any day the source data includes it.

Swan Lake pollen through the year
Three chapters make the Montana pollen year, and Swan Lake follows them in the Northern Rockies order. The tree chapter: river-corridor trees open in late March or April, varying by valley elevation, and run into May. The grass chapter: grasses run from May through July with a June crest, when the hay grasses flower together. The weed chapter: ragweed, sagebrush, wormwood and pigweed run from August until the first hard frost, typically in October.
Valley inversions in western Montana can hold pollen close to town on still mornings, even under famously big, clean-looking skies. Western valleys run a tree-and-grass calendar shaped by rivers and elevation, while the eastern plains add a stronger wind-blown weed and sagebrush finish. The Montana guide singles out sagebrush, flowering late on the dry benches, over a grass summer of timothy, orchard grass, bluegrass and ryegrass.
November falls between the main chapters of the Montana 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 Montana year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Montana allergy season guide.
How to read this index
Pollen Atlas reports the Swan Lake 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 whatever the month. 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.
