Pollen count Parsippany-Troy Hills residents check each morning
The Parsippany-Troy Hills pollen count today is 23 (Low). The main driver is Ragweed, with weed pollen at 30 today. Weed pollen leads the split at 30 (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 Parsippany-Troy Hills 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 Parsippany-Troy Hills
What is driving Parsippany-Troy Hills’s pollen today
The shape of today’s 23 (Low) is set by weed pollen at 30 (Low on its own scale) — about 96% of the four category readings added together, 29.4 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 New Jersey 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 Parsippany-Troy Hills, so the drivers have to be read from the category split above. The New Jersey guide’s account of New Jersey names oak, the spring heavyweight statewide, with maple sharing the stage and birch earning a real billing in the northwestern hills — 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 20 to 23, never changing band. Today’s 23 sits 1 point above the window’s average of 21.8 — a steady window, in which one day reads much like the next.

Parsippany-Troy Hills pollen through the year
Three chapters make the New Jersey pollen year, and Parsippany-Troy Hills 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.
North Jersey runs on New York’s clock and South Jersey on Philadelphia’s slightly earlier one, so the state’s two ends can open their springs weeks apart. The Pine Barrens’ pine pollen coats ponds, cars and porches in yellow dust each spring, but pine grains are comparatively weak allergens; the oaks sharing the Barrens’ canopy are its real contribution. The New Jersey guide singles out oak, the spring heavyweight statewide, with maple sharing the stage and birch earning a real billing in the northwestern hills.
November falls between the main chapters of the New Jersey 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 New Jersey year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the New Jersey allergy season guide.
How to read this index
Pollen Atlas reports the Parsippany-Troy Hills 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 Parsippany-Troy Hills, NJ 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.
