Pollen count New Boston residents check each morning
The New Boston pollen count today is 7 (Low). The main driver is Ragweed, with weed pollen at 9 today. That total sits on a narrow base: weed pollen is 9 while tree pollen is just 0.6 and grass pollen 0.6. Plant-by-plant detail for New Boston, NH follows, along with the outlook for the days ahead. 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 Boston 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.

Pollen by type in New Boston
What is driving New Boston’s pollen today
The shape of today’s 7 (Low) is set by weed pollen at 9 (Low on its own scale) — about 88% of the four category readings added together, 8.4 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 Hampshire weed chapter runs August to September — 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 Boston, so the drivers have to be read from the category split above. The New Hampshire guide’s account of New Hampshire names birch, a signature northern allergen, flowering together with maple and oak in spring — 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 7 to 16, never changing band. Today’s 7 sits 6 points below the window’s average of 13 — a moving window, worth reading day by day rather than from the average.

New Boston pollen through the year
Chapter by chapter, the New Boston pollen year runs like this:
- Alder and maple stir in late March in the south, and the burst crests through April and May — birch above all, with maple and oak — later with every mile north.
- Hayfield and pasture grasses own June and July, cresting around the first hay cutting.
- Ragweed runs August into September and is ended by an early first frost — earliest inland and in the north.
- Mold bookends the year — mud-season stirrings in March and leaf-litter mold returning in the fall — and the coast trades some pollen intensity for fog, damp and summer mold.
The New Hampshire allergy season guide names birch, a signature northern allergen, flowering together with maple and oak in spring. New Hampshire’s season typically runs from late March into October, with its sharpest peak when birch, maple and oak flower together in spring. The Seacoast and the Merrimack Valley run the state’s earliest, most southern clocks, while the White Mountains and the North Country run weeks behind, with late springs, brief summers and the shortest pollen calendar in the state.
November falls between the main chapters of the New Hampshire 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 7 months of the New Hampshire year, March to September — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the New Hampshire allergy season guide.
How to read this index
Pollen Atlas reports the New Boston 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 Boston, NH 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.
