Pollen count Port Sulphur residents check each morning
The Port Sulphur pollen count today is 24 (Low). The main driver is Ragweed, with weed pollen at 27 today. Weed pollen leads the split at 27 (Low on its own scale), followed by tree pollen at 19 and grass pollen at 7. 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 Port Sulphur 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.

Pollen by type in Port Sulphur
What is driving Port Sulphur’s pollen today
The shape of today’s 24 (Low) is set by weed pollen at 27 (Low on its own scale) — about 51% of the four category readings added together, 8 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 Louisiana 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 Port Sulphur, so the drivers have to be read from the category split above. The Louisiana guide’s account of Louisiana names an early February tree start and outdoor mold, elevated much of the year in the Gulf humidity — 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 21 to 24, never changing band. Today’s 24 sits 1 point above the window’s average of 22.8 — a steady window, in which one day reads much like the next.

Port Sulphur pollen through the year
Three chapters make the Louisiana pollen year, and Port Sulphur follows them in the Gulf & South Texas order. The tree chapter: mountain cedar runs from December to March in the west of the region, and oak leads the spring. The grass chapter: grasses carry the hot months, with mold close behind in the Gulf humidity. The weed chapter: ragweed runs from August toward a mild, late finish. Outdoor mold stays elevated for much of the year in the Gulf humidity and can co-headline a reading in any month.
Duration defines Louisiana’s season: hard frosts are infrequent, so the calendar’s true low break is the briefest in the continental interior — and the AAFA’s 2025 report ranked New Orleans No. 2 of 100 metros. The CDC identifies warm, humid environments as prime mold habitat, and Louisiana’s Gulf climate is the continental interior’s clearest example. The Louisiana guide singles out an early February tree start and outdoor mold, elevated much of the year in the Gulf humidity.
November in Port Sulphur sits inside the weed chapter of the Louisiana year, in its closing weeks — the part of the calendar today’s readings should be judged against. Between them, the three chapters touch every month of the Louisiana year — there is no reliably empty month in this calendar. The full calendar is set out in the Louisiana allergy season guide.
How to read this index
Pollen Atlas reports the Port Sulphur 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 Port Sulphur, LA 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.
