Pollen count Bay Harbor Islands residents check each morning
The Bay Harbor Islands pollen count today is 19 (Low). The main driver is Ragweed, with weed pollen at 21 today. Weed pollen leads the split at 21 (Low on its own scale), followed by tree pollen at 14 and grass pollen at 11. 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 weed pollen or mold, reading noticeably higher than the rest, which is why the split is printed on every Bay Harbor Islands 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 Bay Harbor Islands
What is driving Bay Harbor Islands’s pollen today
The shape of today’s 19 (Low) is set by weed pollen at 21 (Low on its own scale) — about 46% of the four category readings added together, 7 points clear of the next category, tree pollen at 14. 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 Bay Harbor Islands, 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 19 to 26, never changing band. Today’s 19 sits 4 points below the window’s average of 23.2 — a moving window, worth reading day by day rather than from the average.

Bay Harbor Islands pollen through the year
Three chapters make the Florida pollen year, and Bay Harbor Islands follows them in the state’s own order. The tree chapter: cedar and then oak open the year, oak beginning as early as February. The grass chapter: grasses run from spring into October or later. The weed chapter: ragweed arrives in late summer and fall, for a shorter window than in the Midwest, alongside a fall mold surge.
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. The Florida guide singles out oak, the signature spring event that often begins in February.
November in Bay Harbor Islands 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 Bay Harbor Islands 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 Bay Harbor Islands, 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.
