Pollen count Key West residents check each morning
The Key West pollen count today is 24 (Low). The main driver is Ragweed, with weed pollen at 26 today. The full split is tree pollen 19, grass pollen 17, weed pollen 26. 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 Key West page.
Florida’s mild climate supports a longer and less sharply divided pollen calendar than most of the United States: tree, grass and weed pollen can each appear across more of the year, and no single month reliably clears the index to zero. Florida pages should therefore be read from their modelled split rather than from a northern seasonal calendar. A low Florida total is a low modelled day, not an off-season guarantee, and the five-day outlook matters more here than in strongly seasonal climates.

Pollen by type in Key West
What is driving Key West’s pollen today
The shape of today’s 24 (Low) is set by weed pollen at 26 (Low on its own scale) — about 42% of the four category readings added together, 7 points clear of the next category, tree pollen at 19. 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 is the Florida calendar working as expected — November falls in the closing weeks of the state’s weed chapter.
Plant-level detail is not in today’s feed for Key West, so the drivers have to be read from the category split above. The Florida guide’s account of Florida names oak, the signature spring event that often begins in February — 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 11 to 24, never changing band. Today’s 24 sits 4 points above the window’s average of 20 — a moving window, worth reading day by day rather than from the average.

Key West pollen through the year
The Key West pollen year runs in chapters, set by its own pattern and the Florida calendar. Trees come first: cedar and then oak open the year, oak beginning as early as February. Grasses take the middle of the year: grasses run from spring into October or later. Weeds close it out: ragweed arrives in late summer and fall, for a shorter window than in the Midwest, alongside a fall mold surge.
The Florida allergy season guide names oak, the signature spring event that often begins in February. Pollen Atlas data shows Miami recording measurable pollen in every month of a typical year — Florida’s calendar rarely clears to zero. Fall in Florida combines its shorter ragweed season with a mold surge from leaf litter and tropical-season rain.
November in Key West sits inside the weed chapter of the Florida year, in its closing weeks — the part of the calendar today’s readings should be judged against. Between them, the three chapters cover 11 months of the Florida year, January to November — a long season by national standards, with only a short quiet gap. The full calendar is set out in the Florida allergy season guide.
How to read this index
Pollen Atlas reports the Key West 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 Key West, FL 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.
