Pollen count Roja residents check each morning
The Roja pollen count today is 17 (Low). The main driver is Ragweed, with weed pollen at 21 today. That total sits on a narrow base: weed pollen is 21 while tree pollen is just 0.6 and grass pollen 7. Plant-by-plant detail for Roja, Latvia 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 Roja 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.

This is the pollen count Roja residents check each morning, built from the day’s tree, grass, weed and mold readings.

Allergies in Roja follow the Latvia 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 Roja 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 Roja allergy forecast: today reads 17 (Low), and the day-by-day outlook shows whether Roja 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 Roja today records is this same combined reading — tree, grass, weed and mold in one index.
The Roja allergy count today is 17 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Roja
What is driving Roja’s pollen today
The shape of today’s 17 (Low) is set by weed pollen at 21 (Low on its own scale) — about 73% of the four category readings added together, 14 points clear of the next category, grass pollen at 7. 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 Latvia weed chapter runs August to September — 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 Roja, so the drivers have to be read from the category split above — it shows how much of today’s total each category is actually carrying, and plant detail returns here automatically on any day the feed includes it.
Across the five-day window the Total Pollen Index runs from 16 to 17, never changing band. Today’s 17 sits 0 points above the window’s average of 16.6 — a steady window, in which one day reads much like the next.
Plants affecting Roja now
Detailed plant-by-plant readings for Roja were not returned in today\u2019s source data, so this section summarises the pollen types the index above is built from instead of listing individual plants.
Tree pollen is one of the categories with a non-zero reading today, at 0.6 (Low).
Grass pollen is one of the categories with a non-zero reading today, at 7 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 21 (Low).
In the Nordic & Baltic North pattern, the plants that typically shape this city’s year are a compressed birch-led spring, a brief early-summer grass peak, and a short late-summer mugwort finish — named here as regional context only, not as today\u2019s measurements.

Roja pollen through the year
Chapter by chapter, the Roja pollen year runs like this:
- The season is compressed: alder stirs first, and birch — the region’s signature spring pollen — peaks through May into early June.
- Grasses own a brief early-summer peak, cresting around the first hay cutting in June and July.
- Mugwort runs through August, and ragweed is scarce at these latitudes — the late window is short and light.
- Mold rises late in the short season, from decaying vegetation as the brief summer closes.
No Latvia allergy season guide is published yet, so this page does not single out signature pollens for Roja — the calendar above is the Nordic & Baltic North regional pattern, and the plant detail on this page names what today’s feed actually records.
November falls between the main chapters of the Latvia 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 6 months of the Latvia year, April to September — a compressed season, which is why its chapters arrive in quick succession. No Latvia allergy season guide is published yet — this calendar follows the Nordic & Baltic North regional pattern. See Roja pollen count rankings and Roja on the pollen heatmap.
How to read this index
Pollen Atlas reports the Roja 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 Roja, Latvia 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.
Roja in today’s national picture
At 17 (Low), Roja ranks joint 60578th of the 90896 cities Pollen Atlas tracks today — in the middle of the national table.

The whole table spans 48 points today — a wide-open day, when the top and bottom of the table are effectively in different seasons.

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Roja resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Roja, Latvia 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.
