Pollen count Mount Crested Butte residents check each morning

The Mount Crested Butte pollen count today is 21 (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 28, weed pollen 0.6. Plant-by-plant detail for Mount Crested Butte, CO follows, along with the outlook for the days ahead. 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 Mount Crested Butte 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.

Pollen by type in Mount Crested Butte

What is driving Mount Crested Butte’s pollen today

The shape of today’s 21 (Low) is set by grass pollen at 28 (Low on its own scale) — about 96% of the four category readings added together, 27.4 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 Colorado 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 Mount Crested Butte, so the drivers have to be read from the category split above. The Colorado guide’s account of Colorado names juniper, arriving ahead of the local tree season, and the ragweed and sagebrush-family weeds of late summer — 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 21 to 24, never changing band. Today’s 21 sits 1 point below the window’s average of 22.2 — a steady window, in which one day reads much like the next.

Mount Crested Butte pollen through the year

Chapter by chapter, the Mount Crested Butte pollen year runs like this:

  • Juniper can arrive in late winter, and the main tree wave builds in spring — as late as April at Denver’s altitude.
  • Grasses follow in a compressed early-summer run.
  • Ragweed and sagebrush-family weeds close the year from late summer.

The Colorado allergy season guide names juniper, arriving ahead of the local tree season, and the ragweed and sagebrush-family weeds of late summer. Altitude compresses Colorado’s season rather than removing it: the waves arrive late — Denver’s tree pollen typically builds in April — and end with early frosts, but they run in a tight sequence. The season ends with the first hard frosts, which stop the late-summer weeds — Denver usually reaches frost in fall, while mountain towns can frost far earlier.

November falls between the main chapters of the Colorado 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 Colorado 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 Colorado allergy season guide.

How to read this index

Pollen Atlas reports the Mount Crested Butte 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.
