What is driving Herron’s pollen today

The shape of today’s 5 (Low) is set by tree pollen at 0.6 (Low on its own scale) — about 33% of the four category readings added together, level with grass pollen at 0.6. Tree readings are the fastest-moving of the four in their season, because species pollinate in sequence — a tree-led total can change character within a week. Tree pollen leading in November runs against the usual calendar — the Montana tree chapter runs March to May — 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 Herron, 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 5 to 5, never changing band. Today’s 5 sits level with the window’s average of 5 — a steady window, in which one day reads much like the next.

Plants affecting Herron now

Detailed plant-by-plant readings for Herron 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 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.

Herron pollen through the year

Three chapters make the Montana pollen year, and Herron 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 Herron 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.
