Pollen count Great Barrington residents check each morning
The Great Barrington pollen count today is 5 (Low). No single plant stands out in today’s readings; the Grass category is the one the index is led by. Tree pollen is the highest single category in the split at 0.6 (Low), ahead of grass pollen at 0.6 and weed 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 tree pollen, reading noticeably higher than the rest, which is why the split is printed on every Great Barrington page.
Outside its main late-spring and early-summer window, grass pollen usually appears as a small background value rather than the driver of the total. A low grass reading alongside a higher weed or mold value is a typical off-peak pattern. Grass should be read from its own value on this page, not assumed from the calendar: the index reports today’s modelled value, and the modelled value outranks any general seasonal expectation.

Pollen by type in Great Barrington
What is driving Great Barrington’s pollen today
The shape of today’s 5 (Low) is set by tree pollen at 0.6 (Low on its own scale) — about 33% of the four category readings added together, level with grass pollen at 0.6. Tree readings are the fastest-moving of the four in their season, because species pollinate in sequence — a tree-led total can change character within a week. Tree pollen leading in November runs against the usual calendar — the Massachusetts tree chapter runs March to May — 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 Great Barrington, 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 5 to 5, never changing band. Today’s 5 sits level with the window’s average of 5 — a steady window, in which one day reads much like the next.

Great Barrington pollen through the year
Three chapters make the Massachusetts pollen year, and Great Barrington 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.
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. The Massachusetts guide singles out birch, opening the spring in April, and oak carrying the peak through May.
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 Great Barrington 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 whatever the month. 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.
