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 Castel di Guido page.
Today’s reading for this city is quiet across the board, and a quiet day is best understood comparatively: the split shows no category carrying the total, and the plant section shows nothing reading high. Seasonal expectations set the background — which pollen types are common in this region at this time of year — but they never override the modelled value. This page reports the modelled reading first, and uses seasonal context only to explain the shape of the numbers it has already shown.

Pollen by type in Castel di Guido
What is driving Castel di Guido’s pollen today
The shape of today’s 22 (Low) is set by tree pollen at 22 (Low on its own scale) — about 79% of the four category readings added together, 17 points clear of the next category, weed pollen at 5. 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 Italy tree chapter runs January 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 Castel di Guido, 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 9 to 22, never changing band. Today’s 22 sits 9 points above the window’s average of 13.2 — a moving window, worth reading day by day rather than from the average.

How to read this index
Pollen Atlas reports the Castel di Guido 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 whatever the month. 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.
