Pollen count New Cassel residents check each morning
The New Cassel pollen count today is 12 (Low). The main driver is Ragweed, with weed pollen at 16 today. The full split is tree pollen 0.6, grass pollen 1, weed pollen 16. 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 New Cassel 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 New Cassel
What is driving New Cassel’s pollen today
The shape of today’s 12 (Low) is set by weed pollen at 16 (Low on its own scale) — about 91% of the four category readings added together, 15 points clear of the next category, grass pollen at 1. 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 York 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 New Cassel, so the drivers have to be read from the category split above. The New York guide’s account of New York names birch and oak, preceded by elm and maple — 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 12 to 28, never changing band. Today’s 12 sits 12 points below the window’s average of 24.4 — a moving window, worth reading day by day rather than from the average.

New Cassel pollen through the year
The New Cassel pollen year runs in chapters, set by the Northeast pattern and the New York 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 New York allergy season guide names birch and oak, preceded by elm and maple. New York City’s tree season typically opens one to three weeks ahead of Rochester’s, where Lake Ontario’s cold air delays spring along the shore. The AAFA’s 2025 report ranked New York City in the less-challenging half of its 100 metros, reflecting moderate overall burden despite a real spring peak.
November falls between the main chapters of the New York 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 York 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 York allergy season guide.
How to read this index
Pollen Atlas reports the New Cassel 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 New Cassel, NY 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.
