Pollen count Decatur residents check each morning
The Decatur pollen count today is 16 (Low). The main driver is Ragweed, with weed pollen at 18 today. Tree pollen is the highest single category in the split at 18 (Low), ahead of weed pollen at 18 and grass pollen at 3. Plant-by-plant detail for Decatur, MS 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 tree pollen, reading noticeably higher than the rest, which is why the split is printed on every Decatur 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 Decatur
What is driving Decatur’s pollen today
The shape of today’s 16 (Low) is set by tree pollen at 18 (Low on its own scale) — about 46% of the four category readings added together, level with weed pollen at 18. 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 Mississippi tree chapter runs February 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 Decatur, so the drivers have to be read from the category split above. The Mississippi guide’s account of Mississippi names oak, pine and hickory in spring — the famous yellow pine dust is highly visible but only part of the spring story — 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 14 to 16, never changing band. Today’s 16 sits 1 point above the window’s average of 15.2 — a steady window, in which one day reads much like the next.

Decatur pollen through the year
Chapter by chapter, the Decatur pollen year runs like this:
- Trees can start as early as February and peak in April.
- Grasses follow in May and run through the summer.
- Ragweed runs from mid-August to the first frost.
- Mold is the quiet fourth player, sustained by river-valley humidity between the pollen waves.
The Mississippi allergy season guide names oak, pine and hickory in spring — the famous yellow pine dust is highly visible but only part of the spring story. Mississippi’s outdoor season can begin with tree pollen in February and stretch into November, among the longest runs anywhere in the United States. The University of Mississippi Medical Center notes that tree pollen has historically posed its biggest threat from early March through April, with grasses following from May into July and ragweed from September through October.
November in Decatur sits inside the weed chapter of the Mississippi year, in its closing weeks — the part of the calendar today’s readings should be judged against. Between them, the three chapters cover 10 months of the Mississippi year, February to November — a long season by national standards, with only a short quiet gap. The full calendar is set out in the Mississippi allergy season guide.
How to read this index
Pollen Atlas reports the Decatur 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 Decatur, MS 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.
