Pollen count Calera residents check each morning

The Calera pollen count today is 21 (Low). The main driver is Ragweed, with weed pollen at 24 today. The full split is tree pollen 13, grass pollen 6, weed pollen 24. 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 weed pollen or mold, reading noticeably higher than the rest, which is why the split is printed on every Calera 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. In the Plains and around the Great Lakes, ragweed is a familiar late-season plant of open ground, field edges and disturbed soil, which is why it so often leads inland autumn readings.

When people ask about Calera allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Calera.

Allergies in Calera follow the Oklahoma calendar set out below — the chapters, the plants behind them, and the 5-day forecast on this page show whether today is typical for the season or an exception to it. If you are checking allergies today in Calera before heading outdoors, the split at the top of this page is the part to read: it shows which pollen is doing the work today, not just how high the total sits.

Read the five-day table on this page as the Calera allergy forecast: today reads 21 (Low), and the day-by-day outlook shows whether Calera allergies are set to ease or build across the week — the days to plan outdoor time around are the ones where the index steps down, not just today.

In practice, the allergy count Calera today records is this same combined reading — tree, grass, weed and mold in one index.

Pollen by type in Calera

What is driving Calera’s pollen today

The shape of today’s 21 (Low) is set by weed pollen at 24 (Low on its own scale) — about 56% of the four category readings added together, 11 points clear of the next category, tree pollen at 13. 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 runs against the usual calendar — the Oklahoma weed chapter runs August to October — 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 Calera, so the drivers have to be read from the category split above. The Oklahoma guide’s account of Oklahoma names ragweed, whose August-to-frost run regularly tops the fall rankings — 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 1 point above the window’s average of 20.2 — a steady window, in which one day reads much like the next.

Plants affecting Calera now

Calera pollen through the year

The Calera pollen year runs in chapters, set by the South-Central Plains pattern and the Oklahoma calendar. Trees come first: river-corridor trees open from February — elm and maple first, then oak and hickory. Grasses take the middle of the year: prairie grasses take over in late May and hold the summer. Weeds close it out: ragweed builds from mid-August to the first hard frost, carried county to county by plains wind. Mold shares the long middle of the year, fed by river-bottom humidity.

The Oklahoma allergy season guide names ragweed, whose August-to-frost run regularly tops the fall rankings. Oklahoma’s season is a relay — trees from February to May, grasses from May to August, ragweed to the first frost — with a mountain cedar influence reaching the south of the state in winter. Pollen Atlas data shows Tulsa regularly topping the fall rankings when ragweed peaks, with Oklahoma City and Wichita often climbing the same rankings in the same weeks.

November falls between the main chapters of the Oklahoma pollen year — the tail of one and the approach of the next — so the calendar alone explains little today, and the modelled split above carries the story. Between them, the three chapters cover 9 months of the Oklahoma year, February to October — leaving a quiet gap of roughly 3 months in the depth of the off-season. The full calendar is set out in the Oklahoma allergy season guide.

How to read this index

Pollen Atlas reports the Calera 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 Calera, OK 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.
