Pollen count Santa Clara residents check each morning
The Santa Clara pollen count today is 22 (Low). The main driver is Ragweed, with weed pollen at 27 today. The full split is tree pollen 13, grass pollen 0.6, weed pollen 27. 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.
Higher-elevation Mountain West cities generally run a shorter outdoor pollen season than the coasts or the South, with the main tree and grass activity compressed into the warmer months. Autumn and winter pages in this region are therefore commonly quiet, with low totals built from small weed and mold values. A low reading in this region and season is the expected pattern, and any future rise will show first in the category split and the forecast, not in the headline alone.

Pollen by type in Santa Clara
What is driving Santa Clara’s pollen today
The shape of today’s 22 (Low) is set by weed pollen at 27 (Low on its own scale) — about 67% of the four category readings added together, 14 points clear of the next category, tree pollen at 13. 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 Utah weed chapter runs August to October — 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 Utah guide’s account of Utah names planted elm, maple, ash and poplars in spring, and chenopod and sagebrush-country weeds at the close — 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 20 to 22, never changing band. Today’s 22 sits 1 point above the window’s average of 21.4 — a steady window, in which one day reads much like the next.
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 27 (Low).
In the Mountain West pattern, the plants that typically shape this city’s year are spring trees and late-spring grasses in a compressed warm-season window — 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 Mountain West pattern and the Utah calendar. Trees come first: juniper can arrive in late winter, and the main tree wave builds in spring — as late as April at Denver’s altitude. Grasses take the middle of the year: grasses follow in a compressed early-summer run. Weeds close it out: ragweed and sagebrush-family weeds close the year from late summer.
The Utah allergy season guide names planted elm, maple, ash and poplars in spring, and chenopod and sagebrush-country weeds at the close. Most Utahns live along the Wasatch Front, in high-desert bowls where winter inversions pool cold air — and the same held-air geography shapes how local pollen lingers. The benches — old lake terraces climbing the foothills — can stand above an inversion pool in cleaner air while the valley floor sits in the murk, so a street’s elevation can matter as much as its trees.
November falls between the main chapters of the Utah 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 Utah year, February to October — leaving a quiet gap of roughly 3 months in the depth of the off-season. The full calendar is set out in the Utah 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.

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