Pollen count Centennial Park residents check each morning
The Centennial Park pollen count today is 19 (Low). The main driver is Ragweed, with weed pollen at 24 today. The full split is tree pollen 8, grass pollen 0.6, weed pollen 24. 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 Centennial Park page.
Desert Southwest pollen does not follow a single national calendar. Arid conditions limit some pollen types for much of the year, while irrigated urban landscaping introduces trees and grasses that would not otherwise grow in the desert, and wind can move pollen across an open landscape efficiently. Readings in this region in particular should be judged against their own split and their own recent days, not against humid-region expectations: a low total here reflects today’s modelled categories, whatever the month.

Pollen by type in Centennial Park
What is driving Centennial Park’s pollen today
The shape of today’s 19 (Low) is set by weed pollen at 24 (Low on its own scale) — about 74% of the four category readings added together, 16 points clear of the next category, tree pollen at 8. 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 Arizona calendar working as expected — November falls in the closing weeks of the state’s weed chapter.
Plant-level detail is not in today’s feed for Centennial Park, so the drivers have to be read from the category split above. The Arizona guide’s account of Arizona names mulberry, ash and olive — planted trees, not wild desert flora — the pollens behind readings of this shape in this state — and the split shows how much of today’s total each category is actually carrying.
Across the five-day window the Total Pollen Index runs from 17 to 19, never changing band. Today’s 19 sits 1 point above the window’s average of 17.6 — a steady window, in which one day reads much like the next.
Plants affecting Centennial Park now

Centennial Park pollen through the year
The Centennial Park pollen year runs in chapters, set by the Desert Southwest pattern and the Arizona calendar. Trees come first: planted trees open in winter — the juniper family and ash first, mulberry at the heart of spring. Grasses take the middle of the year: irrigated Bermuda grass runs long rather than intense, across much of the warm season. Weeds close it out: a final weed wave follows the monsoon rains into fall, with monsoon mold in the same weeks.
The Arizona allergy season guide names mulberry, ash and olive — planted trees, not wild desert flora. Arizona’s season arrives in waves shaped by desert botany and desert weather, with a midsummer heat lull and a mold bump when the monsoon breaks. Phoenix and Tucson often peak weeks apart: Tucson sits at roughly 2,400 feet against Phoenix’s 1,100, and its cooler nights delay its tree wave by a matter of weeks.
November in Centennial Park sits in the overlap of the grass and weed chapters of the Arizona year — overlap weeks, when two chapters feed the same total and the split matters more than the headline. Between them, the three chapters cover 11 months of the Arizona year, January to November — a long season by national standards, with only a short quiet gap. The full calendar is set out in the Arizona allergy season guide.
How to read this index
Pollen Atlas reports the Centennial Park 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.
