Pollen count Mandeville residents check each morning
The Mandeville pollen count today is 21 (Low). The main driver is Ragweed, with weed pollen at 24 today. That total sits on a narrow base: weed pollen is 24 while tree pollen is just 20 and grass pollen 6. Plant-by-plant detail for Mandeville, LA follows, along with the outlook for the days ahead. 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 Mandeville 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 Mandeville
What is driving Mandeville’s pollen today
The shape of today’s 21 (Low) is set by weed pollen at 24 (Low on its own scale) — about 48% of the four category readings added together, 4 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.
Plant-level detail is not in today’s feed for Mandeville, 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 20 to 21, never changing band. Today’s 21 sits 0 points above the window’s average of 20.6 — a steady window, in which one day reads much like the next.

Mandeville pollen through the year
Chapter by chapter, the Mandeville pollen year runs like this:
- Mountain cedar runs from December to March in the west of the region, and oak leads the spring.
- Grasses carry the hot months, with mold close behind in the Gulf humidity.
- 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 Mandeville 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 Mandeville 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 Mandeville, 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.
