Pollen count Birmingham residents check each morning
The Birmingham pollen count today is 20 (Low). The main driver is Ragweed, with weed pollen at 23 today. That total sits on a narrow base: weed pollen is 23 while tree pollen is just 17 and grass pollen 3. Plant-by-plant detail for Birmingham, AL 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 Birmingham 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 Birmingham
What is driving Birmingham’s pollen today
The shape of today’s 20 (Low) is set by weed pollen at 23 (Low on its own scale) — about 53% of the four category readings added together, 6 points clear of the next category, tree pollen at 17. 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 Alabama 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 Birmingham, so the drivers have to be read from the category split above. The Alabama guide’s account of Alabama names oak and hickory, peaking through spring, over a late-winter cedar and juniper opening — 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 18 to 20, never changing band. Today’s 20 sits 1 point above the window’s average of 19.2 — a steady window, in which one day reads much like the next.

Birmingham pollen through the year
Chapter by chapter, the Birmingham 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 Alabama allergy season guide names oak and hickory, peaking through spring, over a late-winter cedar and juniper opening. Alabama’s season is among the longest in the country: tree pollen can start in January on the Gulf Coast, and ragweed can run into October or November before frost ends it. The Asthma and Allergy Foundation of America has placed Birmingham in its national Allergy Capitals rankings, a measure of pollen, medicine use and specialist access combined.
November in Birmingham sits inside the weed chapter of the Alabama 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 Alabama year, February to November — a long season by national standards, with only a short quiet gap. The full calendar is set out in the Alabama allergy season guide.
How to read this index
Pollen Atlas reports the Birmingham 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 Birmingham, AL 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.
