Ruby allergies today

Ruby allergies today are set by the same reading as the pollen count above: the Total Pollen Index is 8 (Low), driven mainly by Ragweed. When people ask about Ruby allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Ruby.

Allergies in Ruby follow the South Carolina calendar set out below — the chapters, the plants behind them, and the 5-day forecast on this page show whether today is typical for the season or an exception to it. If you are checking allergies today in Ruby before heading outdoors, the split at the top of this page is the part to read: it shows which pollen is doing the work today, not just how high the total sits.

Read the five-day table on this page as the Ruby allergy forecast: today reads 8 (Low), and the day-by-day outlook shows whether Ruby allergies are set to ease or build across the week — the days to plan outdoor time around are the ones where the index steps down, not just today.

In practice, the allergy count Ruby today records is this same combined reading — tree, grass, weed and mold in one index.

What is driving Ruby’s pollen today

The shape of today’s 8 (Low) is set by weed pollen at 10 (Low on its own scale) — about 59% of the four category readings added together, 4 points clear of the next category, tree pollen at 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 South Carolina 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 Ruby, so the drivers have to be read from the category split above. The South Carolina guide’s account of South Carolina names oak — the pine dust filming cars in the same weeks is a comparatively weak allergen — 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 8 to 19, never changing band. Today’s 8 sits 9 points below the window’s average of 16.6 — a moving window, worth reading day by day rather than from the average.

Ruby pollen through the year

Chapter by chapter, the Ruby 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 South Carolina allergy season guide names oak — the pine dust filming cars in the same weeks is a comparatively weak allergen. South Carolina’s season opens in February in warm years and can still be going in November in the southern half of the state; Greenville ranked ninth in the AAFA’s 2025 Allergy Capitals report. Warm-season grasses such as Bermuda grass pollinate from late spring deep into summer, with mold layered over the humid middle of the year.

November in Ruby sits inside the weed chapter of the South Carolina 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 South Carolina year, February to November — a long season by national standards, with only a short quiet gap. The full calendar is set out in the South Carolina allergy season guide.

How to read this index

Pollen Atlas reports the Ruby 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 Ruby, SC 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.

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Ruby resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every ragweed season, allergists in Ruby, SC can test whether tree, grass, weed or mold is the category that matters for you — the four readings at the top of this page are the starting point for that conversation.
