Pollen count Denver residents check each morning
The Denver pollen count today is 13 (Low). The main driver is Ragweed, with weed pollen at 17 today. That total sits on a narrow base: weed pollen is 17 while tree pollen is just 0.6 and grass pollen 0.6. Plant-by-plant detail for Denver, PA 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 Denver 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. In the Northeast, autumn weed pollen typically winds down as colder nights arrive, so late-season totals can change quickly from week to week.

If you are checking allergies today in Denver before heading outdoors, the split at the top of this page is the part to read: it shows which pollen is doing the work today, not just how high the total sits.
Read the five-day table on this page as the Denver allergy forecast: today reads 13 (Low), and the day-by-day outlook shows whether Denver allergies are set to ease or build across the week — the days to plan outdoor time around are the ones where the index steps down, not just today.
In practice, the allergy count Denver today records is this same combined reading — tree, grass, weed and mold in one index.

Pollen by type in Denver
What is driving Denver’s pollen today
The shape of today’s 13 (Low) is set by weed pollen at 17 (Low on its own scale) — about 93% of the four category readings added together, 16.4 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 Pennsylvania 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 Denver, so the drivers have to be read from the category split above. The Pennsylvania guide’s account of Pennsylvania names oak, peaking in late April and May, with maple sharing the spring stage — 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 13 to 20, never changing band. Today’s 13 sits 6 points below the window’s average of 18.6 — a moving window, worth reading day by day rather than from the average.
Plants affecting Denver now
Detailed plant-by-plant readings for Denver 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 17 (Low).
In the Northeast pattern, the plants that typically shape this city’s year are spring trees, late-spring grasses and late-summer ragweed — named here as regional context only, not as today\u2019s measurements.
Plant detail returns here automatically on any day the source data includes it.

Denver pollen through the year
Chapter by chapter, the Denver pollen year runs like this:
- Trees open in late March and build to an oak-led peak in May.
- Grasses hold from late May into July.
- Ragweed builds from mid-August, peaks in September, and is ended by the first hard frost.
- Mold tracks the region’s humidity rather than a flowering calendar, and it fills the gaps between chapters.
The Pennsylvania allergy season guide names oak, peaking in late April and May, with maple sharing the spring stage. Pittsburgh and the high plateau run measurably later than Philadelphia: springs start later at elevation, and frosts arrive sooner. Cool-season grasses peak in late May and June, and mold joins the count through the humid mid-Atlantic summer.
November falls between the main chapters of the Pennsylvania 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 Pennsylvania year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Pennsylvania allergy season guide.
How to read this index
Pollen Atlas reports the Denver 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 Denver, PA 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.
Denver in today’s national picture
