Pollen count Longstreet residents check each morning
The Longstreet pollen count today is 16 (Low). The main driver is Ragweed, with weed pollen at 17 today. Tree pollen is the highest single category in the split at 18 (Low), ahead of weed pollen at 17 and grass pollen at 5. 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 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 tree pollen, reading noticeably higher than the rest, which is why the split is printed on every Longstreet 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 Longstreet
What is driving Longstreet’s pollen today
The shape of today’s 16 (Low) is set by tree pollen at 18 (Low on its own scale) — about 45% of the four category readings added together, 1 points clear of the next category, weed pollen at 17. Tree readings are the fastest-moving of the four in their season, because species pollinate in sequence — a tree-led total can change character within a week. Tree pollen leading in November runs against the usual calendar — the Louisiana tree chapter runs December to May — so today’s lead is the model outranking the pattern, and this page reports the modelled reading first.
Plant-level detail is not in today’s feed for Longstreet, 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 15 to 17, never changing band. Today’s 16 sits 0 points above the window’s average of 15.8 — a steady window, in which one day reads much like the next.

Longstreet pollen through the year
The Longstreet 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 Longstreet 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 Longstreet 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 Longstreet, 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.
