Pollen count Camp Pendleton Mainside residents check each morning
The Camp Pendleton Mainside pollen count today is 24 (Low). The main driver is Ragweed, with weed pollen at 27 today. The full split is tree pollen 20, grass pollen 5, weed pollen 27. 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 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 Camp Pendleton Mainside 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 Camp Pendleton Mainside
What is driving Camp Pendleton Mainside’s pollen today
The shape of today’s 24 (Low) is set by weed pollen at 27 (Low on its own scale) — about 52% of the four category readings added together, 7 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 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 Camp Pendleton Mainside, 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 21 to 24, never changing band. Today’s 24 sits 1 point above the window’s average of 23.4 — a steady window, in which one day reads much like the next.

Camp Pendleton Mainside pollen through the year
The Camp Pendleton Mainside pollen year runs in chapters, set by its own pattern and the California calendar. Trees come first: trees build through spring, with planted olive peaking from March into May. Grasses take the middle of the year: grasses peak in spring in the Central Valley and run longer and milder on the coast. Weeds close it out: weeds follow in late summer and fall, stronger after wet winters.
The California allergy season guide names planted olive and the Central Valley’s concentrated spring pollen. 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.
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 Camp Pendleton Mainside 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 Camp Pendleton Mainside, 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.
