Pollen count Donostia / San Sebastián residents check each morning
The Donostia / San Sebastián 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 18 and grass pollen 0.6. Plant-by-plant detail for Donostia / San Sebastián, Spain 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 Donostia / San Sebastián 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 Donostia / San Sebastián
What is driving Donostia / San Sebastián’s pollen today
The shape of today’s 20 (Low) is set by weed pollen at 23 (Low on its own scale) — about 55% of the four category readings added together, 5 points clear of the next category, tree pollen at 18. 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 Spain calendar working as expected — November falls in the closing weeks of the country’s weed chapter.

How to read this index
Pollen Atlas reports the Donostia / San Sebastián 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 Donostia / San Sebastián, Spain 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.
