What is driving Bay Point’s pollen today

The shape of today’s 19 (Low) is set by weed pollen at 22 (Low on its own scale) — about 52% of the four category readings added together, 4 points clear of the next category, tree pollen at 18. 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 runs against the usual calendar — the California weed chapter runs August to October — so today’s lead is the model outranking the pattern, and this page reports the modelled reading first.

Plant-level detail is not in today’s feed for Bay Point, so the drivers have to be read from the category split above. The California guide’s account of California names planted olive and the Central Valley’s concentrated spring pollen — 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 19 to 21, never changing band. Today’s 19 sits 0 points below the window’s average of 19.4 — a steady window, in which one day reads much like the next.

Bay Point pollen through the year

Three chapters make the California pollen year, and Bay Point follows them in the state’s own order. The tree chapter: trees build through spring, with planted olive peaking from March into May. The grass chapter: grasses peak in spring in the Central Valley and run longer and milder on the coast. The weed chapter: weeds follow in late summer and fall, stronger after wet winters.

There is no single California season: the Central Valley records some of the state’s sharpest spring peaks, trapped and concentrated by valley geography, while the coast runs long and mild. The AAFA’s 2025 Allergy Capitals research noted upward movement for several California cities, attributed to grass and weed pollen after wet weather. The California guide singles out planted olive and the Central Valley’s concentrated spring pollen.

November falls between the main chapters of the California pollen year — the tail of one and the approach of the next — so the calendar alone explains little today, and the modelled split above carries the story. Between them, the three chapters cover 9 months of the California year, February to October — leaving a quiet gap of roughly 3 months in the depth of the off-season. The full calendar is set out in the California allergy season guide.

How to read this index

Pollen Atlas reports the Bay Point 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 Bay Point, CA 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.
