Pollen count Petersburg residents check each morning
The Petersburg pollen count today is 27 (Low). The main driver is Ragweed, with weed pollen at 34 today. Weed pollen leads the split at 34 (Low on its own scale), followed by tree pollen at 10 and grass pollen at 2. Below, the plant detail and the multi-day outlook show whether today is the pattern or the exception. 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 Petersburg 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 Petersburg
What is driving Petersburg’s pollen today
The shape of today’s 27 (Low) is set by weed pollen at 34 (Low on its own scale) — about 74% of the four category readings added together, 24 points clear of the next category, tree pollen at 10. 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.
In the plant detail, Ragweed (weed) carries the strongest single plant reading, at a Universal Pollen Index of 1 (Very Low). Ragweed is among the pollens the Texas guide singles out for Texas, so today’s detail lines up with the state’s usual drivers.
Across the five-day window the Total Pollen Index runs from 26 to 27, never changing band. Today’s 27 sits 1 point above the window’s average of 26.4 — a steady window, in which one day reads much like the next.

Petersburg pollen through the year
Three chapters make the Texas pollen year, and Petersburg follows them in the Gulf & South Texas order. The tree chapter: mountain cedar runs from December to March in the west of the region, and oak leads the spring. The grass chapter: grasses carry the hot months, with mold close behind in the Gulf humidity. The weed chapter: 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.
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. The Texas guide singles out mountain cedar — Ashe juniper — in winter, oak in spring and ragweed from August.
November in Petersburg 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 Petersburg 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 Petersburg, 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.
