Pollen count San Simon residents check each morning
The San Simon 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 20 and grass pollen 2. Plant-by-plant detail for San Simon, AZ follows, along with the outlook for the days ahead. Pollen Atlas updated this count on Friday, November 6, 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 Simon 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 San Simon
What is driving San Simon’s pollen today
The shape of today’s 20 (Low) is set by weed pollen at 23 (Low on its own scale) — about 51% of the four category readings added together, 3 points clear of the next category, tree pollen at 20. 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 San Simon, 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 14 to 20, never changing band. Today’s 20 sits 2 points above the window’s average of 18 — a moving window, worth reading day by day rather than from the average.

San Simon pollen through the year
Chapter by chapter, the San Simon pollen year runs like this:
- Planted trees open in winter — the juniper family and ash first, mulberry at the heart of spring.
- Irrigated Bermuda grass runs long rather than intense, across much of the warm season.
- 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 San Simon 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 San Simon 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.
