Pollen count Broad Brook residents check each morning
The Broad Brook pollen count today is 10 (Low). The main driver is Ragweed, with weed pollen at 13 today. That total sits on a narrow base: weed pollen is 13 while tree pollen is just 0.6 and grass pollen 0.6. Plant-by-plant detail for Broad Brook, CT 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 Broad Brook 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 Broad Brook
What is driving Broad Brook’s pollen today
The shape of today’s 10 (Low) is set by weed pollen at 13 (Low on its own scale) — about 92% of the four category readings added together, 12.4 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 Connecticut 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 Broad Brook, so the drivers have to be read from the category split above. The Connecticut guide’s account of Connecticut names oak, the spring heavyweight peaking in May, with birch alongside — 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 10 to 23, never changing band. Today’s 10 sits 8 points below the window’s average of 17.8 — a moving window, worth reading day by day rather than from the average.

Broad Brook pollen through the year
Chapter by chapter, the Broad Brook 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 Connecticut allergy season guide names oak, the spring heavyweight peaking in May, with birch alongside. Connecticut’s season runs from late March to the first hard frost in three clear acts, and the Connecticut River Valley’s farm bottomlands give Hartford a fall ragweed peak to match its spring. The shore trades a little pollen relief from Sound breezes for elevated mold, while the northwest hills start latest and finish earliest.
November falls between the main chapters of the Connecticut 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 Connecticut year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Connecticut allergy season guide.
How to read this index
Pollen Atlas reports the Broad Brook 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 Broad Brook, CT 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.
