Pollen count Deerfield residents check each morning
The Deerfield pollen count today is 8 (Low). The main driver is Ragweed, with weed pollen at 10 today. That total sits on a narrow base: weed pollen is 10 while tree pollen is just 0.6 and grass pollen 0.6. Plant-by-plant detail for Deerfield, MA follows, along with the outlook for the days ahead. 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 Deerfield 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 Deerfield
What is driving Deerfield’s pollen today
The shape of today’s 8 (Low) is set by weed pollen at 10 (Low on its own scale) — about 89% of the four category readings added together, 9.4 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 Massachusetts 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 Deerfield, so the drivers have to be read from the category split above. The Massachusetts guide’s account of Massachusetts names birch, opening the spring in April, and oak carrying the peak through May — 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 8 to 18, never changing band. Today’s 8 sits 6 points below the window’s average of 13.6 — a moving window, worth reading day by day rather than from the average.

Deerfield pollen through the year
Chapter by chapter, the Deerfield pollen year runs like this:
- Trees open in late March and build to an oak-led peak in May.
- Grasses hold from late May into July.
- 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 Massachusetts allergy season guide names birch, opening the spring in April, and oak carrying the peak through May. Massachusetts runs three overlapping springs — coast, Connecticut River valley and Berkshire high ground — which can trail one another by weeks. Grass holds the middle of the year, from late May into July, with the western counties’ hay country adding an agricultural source the suburbs never see.
November falls between the main chapters of the Massachusetts 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 Massachusetts year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Massachusetts allergy season guide.
How to read this index
Pollen Atlas reports the Deerfield 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 Deerfield, MA 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.
