Pollen count Hempstead residents check each morning
The Hempstead pollen count today is 21 (Low). The main driver is Ragweed, with weed pollen at 23 today. The full split is tree pollen 20, grass pollen 9, weed pollen 23. 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 Friday, November 6, 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 Hempstead 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 Hempstead
What is driving Hempstead’s pollen today
The shape of today’s 21 (Low) is set by weed pollen at 23 (Low on its own scale) — about 44% of the four category readings added together, 3 points clear of the next category, tree pollen at 20. 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 Hempstead, 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 14 to 21, never changing band. Today’s 21 sits 2 points above the window’s average of 19.4 — a moving window, worth reading day by day rather than from the average.

Hempstead pollen through the year
The Hempstead 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 Hempstead 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 Hempstead 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 Hempstead, 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.
