Pollen count Santa Clara residents check each morning
The Santa Clara pollen count today is 17 (Low). The main driver is Ragweed, with weed pollen at 20 today. The full split is tree pollen 12, grass pollen 0.6, weed pollen 20. 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 Saturday, November 7, 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 Santa Clara 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.

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

Pollen by type in Santa Clara
What is driving Santa Clara’s pollen today
The shape of today’s 17 (Low) is set by weed pollen at 20 (Low on its own scale) — about 61% of the four category readings added together, 8 points clear of the next category, tree pollen at 12. 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 Oregon 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 Santa Clara, so the drivers have to be read from the category split above. The Oregon guide’s account of Oregon names alder and hazelnut early, then the Willamette Valley’s seed grasses — 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 17, never changing band. Today’s 17 sits 3 points above the window’s average of 13.6 — a moving window, worth reading day by day rather than from the average.
Plants affecting Santa Clara now
Detailed plant-by-plant readings for Santa Clara 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 20 (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.

Santa Clara pollen through the year
The Santa Clara pollen year runs in chapters, set by the Pacific Northwest pattern and the Oregon 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 Oregon allergy season guide names alder and hazelnut early, then the Willamette Valley’s seed grasses. The Willamette Valley grows almost two-thirds of the United States’ cool-season grass seed, and its grass peak ends when the mid-summer harvest cuts the fields and removes the source. East of the Cascades, western juniper’s late-winter-to-spring pollen opens a shorter, compressed high-desert season.
November falls between the main chapters of the Oregon 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 Oregon 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 Oregon allergy season guide.
How to read this index
Pollen Atlas reports the Santa Clara 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.
