What is driving Brownsville’s pollen today

The shape of today’s 10 (Low) is set by weed pollen at 11 (Low on its own scale) — about 46% of the four category readings added together, 3 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 Brownsville, 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 9 to 14, never changing band. Today’s 10 sits 1 point below the window’s average of 10.6 — a steady window, in which one day reads much like the next.

Brownsville pollen through the year

The Brownsville pollen year runs in chapters, set by the Gulf & South Texas pattern and the Texas calendar. Trees come first: mountain cedar runs from December to March in the west of the region, and oak leads the spring. Grasses take the middle of the year: grasses carry the hot months, with mold close behind in the Gulf humidity. Weeds close it out: 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 Brownsville 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 Brownsville 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 Brownsville, 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.
