Pollen count Cornwall residents check each morning
The Cornwall 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 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 tree pollen, reading noticeably higher than the rest, which is why the split is printed on every Cornwall 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.

This is the pollen count Cornwall residents check each morning, built from the day’s tree, grass, weed and mold readings.

Cornwall allergies today
Cornwall allergies today are set by the same reading as the pollen count above: the Total Pollen Index is 5 (Low), driven mainly by Grass. When people ask about Cornwall allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Cornwall.
Allergies in Cornwall follow the Connecticut calendar set out below — the chapters, the plants behind them, and the 5-day forecast on this page show whether today is typical for the season or an exception to it. If you are checking allergies today in Cornwall before heading outdoors, the split at the top of this page is the part to read: it shows which pollen is doing the work today, not just how high the total sits.
Read the five-day table on this page as the Cornwall allergy forecast: today reads 5 (Low), and the day-by-day outlook shows whether Cornwall allergies are set to ease or build across the week — the days to plan outdoor time around are the ones where the index steps down, not just today.
In practice, the allergy count Cornwall today records is this same combined reading — tree, grass, weed and mold in one index.
The Cornwall allergy count today is 5 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Cornwall
What is driving Cornwall’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 Connecticut 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 Cornwall, 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 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.
Plants affecting Cornwall now
Detailed plant-by-plant readings for Cornwall were not returned in today\u2019s source data, so this section summarises the pollen types the index above is built from instead of listing individual plants.
Tree pollen is one of the categories with a non-zero reading today, at 0.6 (Low).
Grass pollen is one of the categories with a non-zero reading today, at 0.6 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 0.6 (Low).
In the Northeast pattern, the plants that typically shape this city’s year are spring trees, late-spring grasses and late-summer ragweed — named here as regional context only, not as today\u2019s measurements.
Plant detail returns here automatically on any day the source data includes it.

Cornwall pollen through the year
Three chapters make the Connecticut pollen year, and Cornwall 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.
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. The Connecticut guide singles out oak, the spring heavyweight peaking in May, with birch alongside.
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 Cornwall 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.
Cornwall in today’s national picture
At 5 (Low), Cornwall ranks joint 86157th of the 90896 cities Pollen Atlas tracks today — in the middle of the national table. The highest reading in the country today is Serpa, Portugal at 53, and the lowest is Galiakberovo, Russia at 5. The whole table spans 48 points today — a wide-open day, when the top and bottom of the table are effectively in different seasons.
Around Cornwall: West Cornwall, CT (2 miles away) reads 5 (Low); Cornwall Bridge, CT (4 miles away) reads 5 (Low); Sharon, CT (7 miles away) reads 7 (Low). Cornwall reads exactly level with its nearest tracked neighbour today. Across Connecticut’s 215 tracked cities, today runs from 5 in Essex Village to 10 in Rockville.
Pollen totals are population numbers; symptoms are personal. The same reading can leave one Cornwall resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Cornwall, CT can test whether tree, grass, weed or mold is the category that matters for you — the four readings at the top of this page are the starting point for that conversation.
