Pollen count Twin Falls residents check each morning

The Twin Falls pollen count today is 20 (Low). The main driver is Ragweed, with weed pollen at 26 today. The full split is tree pollen 0.6, grass pollen 0.6, weed pollen 26. The sections below break that headline number down by plant, by day and by what the band means in practice. 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 Twin Falls page.

Higher-elevation Mountain West cities generally run a shorter outdoor pollen season than the coasts or the South, with the main tree and grass activity compressed into the warmer months. Autumn and winter pages in this region are therefore commonly quiet, with low totals built from small weed and mold values. A low reading in this region and season is the expected pattern, and any future rise will show first in the category split and the forecast, not in the headline alone.

This is the pollen count Twin Falls residents check each morning, built from the day’s tree, grass, weed and mold readings.

Pollen by type in Twin Falls

What is driving Twin Falls’s pollen today

The shape of today’s 20 (Low) is set by weed pollen at 26 (Low on its own scale) — about 96% of the four category readings added together, 25.4 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 Idaho 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 Twin Falls, so the drivers have to be read from the category split above. The Idaho guide’s account of Idaho names sagebrush, the signature weed of the Snake River plain from August through October — 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 18 to 20, never changing band. Today’s 20 sits 1 point above the window’s average of 19.2 — a steady window, in which one day reads much like the next.

Plants affecting Twin Falls now

Twin Falls pollen through the year

The Twin Falls pollen year runs in chapters, set by the Mountain West pattern and the Idaho calendar. Trees come first: juniper can arrive in late winter, and the main tree wave builds in spring — as late as April at Denver’s altitude. Grasses take the middle of the year: grasses follow in a compressed early-summer run. Weeds close it out: ragweed and sagebrush-family weeds close the year from late summer.

The Idaho allergy season guide names sagebrush, the signature weed of the Snake River plain from August through October. Southwest Idaho’s working calendar runs trees from February to May, grasses from May to July, and weeds from August — and elevation delays everything, so the eastern high country starts later and ends earlier than the Treasure Valley. The northern panhandle is a different regime — wetter and forested, with pine, cedar and alder in spring and a softer sagebrush presence.

November falls between the main chapters of the Idaho 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 9 months of the Idaho year, February to October — leaving a quiet gap of roughly 3 months in the depth of the off-season. The full calendar is set out in the Idaho allergy season guide.

How to read this index

Pollen Atlas reports the Twin Falls 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.
