Pollen count Calderara di Reno residents check each morning
The Calderara di Reno pollen count today is 11 (Low). The main driver is Ragweed, with weed pollen at 14 today. That total sits on a narrow base: weed pollen is 14 while tree pollen is just 3 and grass pollen 0.6. Plant-by-plant detail for Calderara di Reno, Italy follows, along with the outlook for the days ahead. Pollen Atlas updated this count on Saturday, November 7, 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 Calderara di Reno 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 Calderara di Reno
What is driving Calderara di Reno’s pollen today
The shape of today’s 11 (Low) is set by weed pollen at 14 (Low on its own scale) — about 80% of the four category readings added together, 11 points clear of the next category, tree pollen at 3. 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 Italy calendar working as expected — November falls in the closing weeks of the country’s weed chapter.
Plant-level detail is not in today’s feed for Calderara di Reno, so the drivers have to be read from the category split above — it shows how much of today’s total each category is actually carrying, and plant detail returns here automatically on any day the feed includes it.
Across the five-day window the Total Pollen Index runs from 11 to 27, never changing band. Today’s 11 sits 9 points below the window’s average of 20 — a moving window, worth reading day by day rather than from the average.

How to read this index
Pollen Atlas reports the Calderara di Reno 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 Calderara di Reno, Italy 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.
