Pollen count Casal Novo residents check each morning
The Casal Novo pollen count today is 10 (Low). The main driver is Ragweed, with weed pollen at 5 today. Tree pollen is the highest single category in the split at 10 (Low), ahead of weed pollen at 5 and grass pollen at 1. Plant-by-plant detail for Casal Novo, Portugal follows, along with the outlook for the days ahead. Pollen Atlas updated this count on Monday, November 9, 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 Casal Novo 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 Casal Novo
What is driving Casal Novo’s pollen today
The shape of today’s 10 (Low) is set by tree pollen at 10 (Low on its own scale) — about 63% of the four category readings added together, 5 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 Portugal 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 Casal Novo, 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 8 to 10, never changing band. Today’s 10 sits 1 point above the window’s average of 8.8 — a steady window, in which one day reads much like the next.

How to read this index
Pollen Atlas reports the Casal Novo 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 Casal Novo, Portugal 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.
