Pollen count Silvana residents check each morning
The Silvana pollen count today is 12 (Low). The main driver is Ragweed, with weed pollen at 14 today. The full split is tree pollen 9, grass pollen 0.6, weed pollen 14. 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 Silvana page.
In the Pacific Northwest, the main outdoor pollen activity is concentrated in spring and early summer — trees first, then grasses — and readings outside that window are commonly low across every category. Cool-season pages in this region are therefore often defined by what is absent: zero or near-zero tree and grass values, with any remaining total carried by small weed or mold readings. That quiet pattern is itself useful information, and it is reported here exactly as modelled.
To see whether today’s pollen level holds, check the 5-day Silvana pollen forecast below — it is currently mixed, with Monday the highest day in the window.
This is the pollen count Silvana residents check each morning, built from the day’s tree, grass, weed and mold readings.

Allergies in Silvana follow the Washington 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 Silvana 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 Silvana allergy forecast: today reads 12 (Low), and the day-by-day outlook shows whether Silvana 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 Silvana today records is this same combined reading — tree, grass, weed and mold in one index.
The Silvana allergy count today is 12 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Silvana
What is driving Silvana’s pollen today
The shape of today’s 12 (Low) is set by weed pollen at 14 (Low on its own scale) — about 59% of the four category readings added together, 5 points clear of the next category, tree pollen at 9. 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 Washington 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 Silvana, so the drivers have to be read from the category split above. The Washington guide’s account of Washington names alder and hazelnut from January on the west side, and timothy and sagebrush on Spokane’s continental clock — 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 7 to 13, never changing band. Today’s 12 sits 1 point above the window’s average of 10.6 — a moving window, worth reading day by day rather than from the average.
Plants affecting Silvana now
Detailed plant-by-plant readings for Silvana 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.

Grass pollen is one of the categories with a non-zero reading today, at 0.6 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 14 (Low).
In the Pacific Northwest pattern, the plants that typically shape this city’s year are spring trees and late-spring grasses in the Pacific Northwest pattern — named here as regional context only, not as today\u2019s measurements.

Silvana pollen through the year
The Silvana pollen year runs in chapters, set by the Pacific Northwest pattern and the Washington calendar. Trees come first: alder and hazelnut can start in January west of the Cascades, with maple and oak following through April and May. Grasses take the middle of the year: grasses run from May, peaking in late spring and early summer. Weeds close it out: weeds are the minor act — sagebrush and tumbleweed east of the Cascades carry into September. Mold is the wet-season constant west of the Cascades, where rain crashes counts and the season restarts on the first dry, mild day.
The Washington allergy season guide names alder and hazelnut from January on the west side, and timothy and sagebrush on Spokane’s continental clock. Washington’s pollen season now starts about 20 days earlier and lasts almost a month longer than 30 years ago, according to the state Department of Health. UW Medicine specialists put the start of Seattle’s tree pollen season at around mid-February in a typical year.
November falls between the main chapters of the Washington 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 Washington year, January to September — leaving a quiet gap of roughly 3 months in the depth of the off-season. The full calendar is set out in the Washington allergy season guide.
How to read this index
Pollen Atlas reports the Silvana 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 whatever the month. 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 Silvana resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Silvana, WA 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.
