What is driving Somerton’s pollen today

The shape of today’s 33 (Low) is set by weed pollen at 40 (Low on its own scale) — about 63% of the four category readings added together, 21 points clear of the next category, tree pollen at 19. 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 Somerton, 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 32 to 33, never changing band. Today’s 33 sits 0 points above the window’s average of 32.6 — a steady window, in which one day reads much like the next.

Somerton pollen through the year

Chapter by chapter, the Somerton 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 Somerton 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 Somerton 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.
