Pollen count Fair Oaks residents check each morning
The Fair Oaks pollen count today is 19 (Low). The main driver is Ragweed, with weed pollen at 25 today. That total sits on a narrow base: weed pollen is 25 while tree pollen is just 0.6 and grass pollen 0.6. Plant-by-plant detail for Fair Oaks, VA 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 Fair Oaks 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 Fair Oaks
What is driving Fair Oaks’s pollen today
The shape of today’s 19 (Low) is set by weed pollen at 25 (Low on its own scale) — about 95% of the four category readings added together, 24.4 points clear of the next category, tree pollen at 0.6. 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 Virginia 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 Fair Oaks, so the drivers have to be read from the category split above. The Virginia guide’s account of Virginia names a spring tree crest and a fall ragweed season joined by a summer grass bridge — 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 28, never changing band. Today’s 19 sits 7 points below the window’s average of 25.8 — a moving window, worth reading day by day rather than from the average.

Fair Oaks pollen through the year
Chapter by chapter, the Fair Oaks pollen year runs like this:
- Trees can start as early as February and peak in April.
- Grasses follow in May and run through the summer.
- Ragweed runs from mid-August to the first frost.
- Mold is the quiet fourth player, sustained by river-valley humidity between the pollen waves.
The Virginia allergy season guide names a spring tree crest and a fall ragweed season joined by a summer grass bridge. The mid-Atlantic spring crest moves inland and uphill: coastal readings crest first, Piedmont readings follow, and mountain readings trail by one to two weeks in most years. The AAFA has ranked Virginia’s capital region among the more challenging US metros in its annual Allergy Capitals assessments.
November in Fair Oaks sits inside the weed chapter of the Virginia year, in its closing weeks — the part of the calendar today’s readings should be judged against. Between them, the three chapters cover 10 months of the Virginia year, February to November — a long season by national standards, with only a short quiet gap. The full calendar is set out in the Virginia allergy season guide.
How to read this index
Pollen Atlas reports the Fair Oaks 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 Fair Oaks, VA 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.
