Pollen count Chevy Chase Heights residents check each morning
The Chevy Chase Heights pollen count today is 11 (Low). The main driver is Ragweed, with weed pollen at 14 today. Weed pollen leads the split at 14 (Low on its own scale), followed by tree pollen at 0.6 and grass pollen at 0.6. Below, the plant detail and the multi-day outlook show whether today is the pattern or the exception. 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 Chevy Chase Heights 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 Chevy Chase Heights
What is driving Chevy Chase Heights’s pollen today
The shape of today’s 11 (Low) is set by weed pollen at 14 (Low on its own scale) — about 92% of the four category readings added together, 13.4 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 Chevy Chase Heights, 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 11 to 15, never changing band. Today’s 11 sits 3 points below the window’s average of 14.2 — a steady window, in which one day reads much like the next.

Chevy Chase Heights pollen through the year
Three chapters make the Pennsylvania pollen year, and Chevy Chase Heights follows them in the Northeast order. The tree chapter: trees open in late March and build to an oak-led peak in May. The grass chapter: grasses hold from late May into July. The weed chapter: 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.
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. The Pennsylvania guide singles out oak, peaking in late April and May, with maple sharing the spring stage.
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 Chevy Chase Heights 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 Chevy Chase Heights, 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.
