Pollen count Donaldson residents check each morning
The Donaldson pollen count today is 15 (Low). The main driver is Ragweed, with weed pollen at 20 today. The full split is tree pollen 0.6, grass pollen 0.6, weed pollen 20. 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 Donaldson 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.

Pollen by type in Donaldson
What is driving Donaldson’s pollen today
The shape of today’s 15 (Low) is set by weed pollen at 20 (Low on its own scale) — about 94% of the four category readings added together, 19.4 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 Donaldson, 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 15, never changing band. Today’s 15 sits 0 points above the window’s average of 14.6 — a steady window, in which one day reads much like the next.
Plants affecting Donaldson now
Detailed plant-by-plant readings for Donaldson 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.

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 20 (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.

Donaldson pollen through the year
The Donaldson pollen year runs in chapters, set by the Northeast pattern and the Pennsylvania calendar. Trees come first: trees open in late March and build to an oak-led peak in May. Grasses take the middle of the year: grasses hold from late May into July. Weeds close it out: 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 Donaldson 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 Donaldson, 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.
