Pollen count San Pedro residents check each morning
The San Pedro pollen count today is 11 (Low). The main driver is Ragweed, with weed pollen at 13 today. That total sits on a narrow base: weed pollen is 13 while tree pollen is just 8 and grass pollen 5. Plant-by-plant detail for San Pedro, TX follows, along with the outlook for the days ahead. 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 San Pedro 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.

Pollen by type in San Pedro
What is driving San Pedro’s pollen today
The shape of today’s 11 (Low) is set by weed pollen at 13 (Low on its own scale) — about 50% of the four category readings added together, 5 points clear of the next category, tree pollen at 8. 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 Texas 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 San Pedro, so the drivers have to be read from the category split above. The Texas guide’s account of Texas names mountain cedar — Ashe juniper — in winter, oak in spring and ragweed from August — 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 10 to 16, never changing band. Today’s 11 sits 1 point below the window’s average of 11.8 — a moving window, worth reading day by day rather than from the average.

San Pedro pollen through the year
Chapter by chapter, the San Pedro pollen year runs like this:
- Mountain cedar runs from December to March in the west of the region, and oak leads the spring.
- Grasses carry the hot months, with mold close behind in the Gulf humidity.
- Ragweed runs from August toward a mild, late finish.
- Outdoor mold stays elevated for much of the year in the Gulf humidity and can co-headline a reading in any month.
The Texas allergy season guide names mountain cedar — Ashe juniper — in winter, oak in spring and ragweed from August. Texas runs four seasons back to back — cedar from December to March, oak and other trees in spring, grasses through summer, ragweed to the first frost — so its true low window is short. Pollen seasons are generally growing longer and more intense across the Northern Hemisphere, research by Ziska and colleagues (2019) found — a trend Texas’s near-year-round calendar already illustrates.
November in San Pedro sits inside the weed chapter of the Texas year, in its closing weeks — the part of the calendar today’s readings should be judged against. Between them, the three chapters touch every month of the Texas year — there is no reliably empty month in this calendar. The full calendar is set out in the Texas allergy season guide.
How to read this index
Pollen Atlas reports the San Pedro 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 San Pedro, TX 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.
