Pollen count Gustavia residents check each morning
The Gustavia pollen count today is 40 (Moderate). The main driver is Ragweed, with weed pollen at 40 today. Weed pollen leads the split at 40 (Moderate on its own scale), followed by grass pollen at 33 and tree pollen at 14. 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 14, 2026.
A Moderate band means the Total Pollen Index sits in the middle of the 0–100 scale — neither a quiet day nor a peak day. On moderate days the split usually explains the total: one or two categories do most of the work while the others stay low. The Gustavia split above shows exactly which categories those are today, and the forecast below shows whether the moderate reading is a plateau or a step toward a higher band.
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.

Pollen by type in Gustavia
What is driving Gustavia’s pollen today
The shape of today’s 40 (Moderate) is set by weed pollen at 40 (Moderate on its own scale) — about 46% of the four category readings added together, 7 points clear of the next category, grass pollen at 33. 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 a modelled reading, reported as modelled — no regional calendar is asserted for Saint Barthelemy, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for Gustavia, so the drivers have to be read from the category split above — it shows how much of today’s total each category is actually carrying, and plant detail returns here automatically on any day the feed includes it.
Across the five-day window the Total Pollen Index runs from 28 to 40, never changing band. Today’s 40 sits 4 points above the window’s average of 36.2 — a moving window, worth reading day by day rather than from the average.

Gustavia pollen through the year
Three chapters make the Saint Barthelemy pollen year, and Gustavia follows them in the Global order. The tree chapter: tree pollen seasons vary with local climate and vegetation, so this page reports the measured readings first and treats any calendar as background only. The grass chapter: grass pollen seasons vary with local climate and vegetation, and the measured value outranks any general seasonal expectation. The weed chapter: weed pollen seasons vary with local climate and vegetation, and no regional calendar is asserted for this area.
No Saint Barthelemy allergy season guide is published yet, so this page does not single out signature pollens for Gustavia — the calendar above is the Global regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Gustavia is reported from its modelled readings, not from a regional calendar — no regional calendar is asserted for Saint Barthelemy, so the calendar alone explains little today, and the modelled split above carries the story. No Saint Barthelemy allergy season guide is published yet — this calendar follows the Global regional pattern. See Gustavia pollen count rankings and Gustavia on the pollen heatmap.
How to read this index
Pollen Atlas reports the Gustavia 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 Gustavia, Saint Barthelemy 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.
