Pollen count Hahnville residents check each morning
The Hahnville pollen count today is 22 (Low). The main driver is Ragweed, with weed pollen at 25 today. The full split is tree pollen 20, grass pollen 8, weed pollen 25. 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 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 Hahnville 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 Hahnville
What is driving Hahnville’s pollen today
The shape of today’s 22 (Low) is set by weed pollen at 25 (Low on its own scale) — about 47% of the four category readings added together, 5 points clear of the next category, tree pollen at 20. 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.
In the plant detail, Ragweed (weed) carries the strongest single plant reading, at a Universal Pollen Index of 2 (Low), followed by Elm at 1. None of the plants in today’s detail is one of the state guide’s signature names for Louisiana — a single day’s detail and a season’s pattern are different lenses, and both are printed on this page for that reason.
Across the five-day window the Total Pollen Index runs from 19 to 22, never changing band. Today’s 22 sits 1 point above the window’s average of 20.8 — a steady window, in which one day reads much like the next.

Hahnville pollen through the year
The Hahnville pollen year runs in chapters, set by the Gulf & South Texas pattern and the Louisiana calendar. Trees come first: mountain cedar runs from December to March in the west of the region, and oak leads the spring. Grasses take the middle of the year: grasses carry the hot months, with mold close behind in the Gulf humidity. Weeds close it out: 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.
The Louisiana allergy season guide names an early February tree start and outdoor mold, elevated much of the year in the Gulf humidity. 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.
November in Hahnville 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 Hahnville 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 Hahnville, 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.
