Pollen count Biddeford residents check each morning
The Biddeford pollen count today is 6 (Low). The main driver is Ragweed, with weed pollen at 8 today. The full split is tree pollen 0.6, grass pollen 0.6, weed pollen 8. 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 Friday, November 6, 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 Biddeford 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 Biddeford
What is driving Biddeford’s pollen today
The shape of today’s 6 (Low) is set by weed pollen at 8 (Low on its own scale) — about 87% of the four category readings added together, 7.4 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 Maine 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 Biddeford, so the drivers have to be read from the category split above. The Maine guide’s account of Maine names birch, a signature spring pollen, released with maple and oak in a rapid April and May burst — 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 6 to 14, never changing band. Today’s 6 sits 4 points below the window’s average of 9.8 — a moving window, worth reading day by day rather than from the average.

Biddeford pollen through the year
The Biddeford pollen year runs in chapters, set by the Northern New England pattern and the Maine calendar. Trees come first: 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. Grasses take the middle of the year: hayfield and pasture grasses own June and July, cresting around the first hay cutting. Weeds close it out: 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 Maine allergy season guide names birch, a signature spring pollen, released with maple and oak in a rapid April and May burst. Maine’s season is lengthening: Portland’s freeze-free growing season has expanded by about 16 days since 1970, according to WGME meteorologists’ reporting of climate data. The coast trades some pollen intensity for fog, damp and summer mold, while inland valleys get warmer, stiller air and the forest’s full output.
November falls between the main chapters of the Maine 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 Maine year, March to September — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Maine allergy season guide.
How to read this index
Pollen Atlas reports the Biddeford 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 Biddeford, ME 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.
