Pollen count Iztacalco residents check each morning
The Iztacalco pollen count today is 17 (Low). The main driver is Ragweed, with weed pollen at 19 today. The full split is tree pollen 14, grass pollen 6, weed pollen 19. The sections below break that headline number down by plant, by day and by what the band means in practice. 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 Iztacalco 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 Iztacalco
What is driving Iztacalco’s pollen today
The shape of today’s 17 (Low) is set by weed pollen at 19 (Low on its own scale) — about 49% of the four category readings added together, 5 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 Iztacalco, 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 15 to 23, never changing band. Today’s 17 sits 2 points below the window’s average of 18.6 — a moving window, worth reading day by day rather than from the average.

Iztacalco pollen through the year
The Iztacalco pollen year runs in chapters, set by the Global pattern and the Mexico calendar. Trees come first: tree pollen seasons vary with local climate and vegetation, so this page reports the measured readings first and treats any calendar as background only. Grasses take the middle of the year: grass pollen seasons vary with local climate and vegetation, and the measured value outranks any general seasonal expectation. Weeds close it out: weed pollen seasons vary with local climate and vegetation, and no regional calendar is asserted for this area.
No Mexico allergy season guide is published yet, so this page does not single out signature pollens for Iztacalco — the calendar above is the Global regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Iztacalco is reported from its modelled readings, not from a regional calendar — no regional calendar is asserted for Mexico, so the calendar alone explains little today, and the modelled split above carries the story. No Mexico allergy season guide is published yet — this calendar follows the Global regional pattern. See Iztacalco pollen count rankings and Iztacalco on the pollen heatmap.
How to read this index
Pollen Atlas reports the Iztacalco 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 Iztacalco, 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.
