Pollen count San Cristóbal de las Casas residents check each morning
The San Cristóbal de las Casas pollen count today is 15 (Low). The main driver is Ragweed, with weed pollen at 17 today. Weed pollen leads the split at 17 (Low on its own scale), followed by tree pollen at 14 and grass pollen at 3. Below, the plant detail and the multi-day outlook show whether today is the pattern or the exception. 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 San Cristóbal de las Casas 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 San Cristóbal de las Casas
What is driving San Cristóbal de las Casas’s pollen today
The shape of today’s 15 (Low) is set by weed pollen at 17 (Low on its own scale) — about 50% of the four category readings added together, 3 points clear of the next category, tree pollen at 14. 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 a modelled reading, reported as modelled — no regional calendar is asserted for Mexico, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for San Cristóbal de las Casas, 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 20, never changing band. Today’s 15 sits 1 point above the window’s average of 14.2 — a moving window, worth reading day by day rather than from the average.

The weed chapter: weed pollen seasons vary with local climate and vegetation, and no regional calendar is asserted for this area.

How to read this index
Pollen Atlas reports the San Cristóbal de las Casas 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 San Cristóbal de las Casas, Mexico 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.
