Pollen count Newcastle residents check each morning
The Newcastle pollen count today is 21 (Low). The main driver is Ragweed, with weed pollen at 24 today. The full split is tree pollen 16, grass pollen 6, weed pollen 24. 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 Newcastle 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 Newcastle
What is driving Newcastle’s pollen today
The shape of today’s 21 (Low) is set by weed pollen at 24 (Low on its own scale) — about 52% of the four category readings added together, 8 points clear of the next category, tree pollen at 16. 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 Newcastle, 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 20 to 21, never changing band. Today’s 21 sits 0 points above the window’s average of 20.6 — a steady window, in which one day reads much like the next.
Plants affecting Newcastle now
Detailed plant-by-plant readings for Newcastle 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.
Tree pollen is one of the categories with a non-zero reading today, at 16 (Low).
Grass pollen is one of the categories with a non-zero reading today, at 6 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 24 (Low).
In the Gulf & South Texas pattern, the plants that typically shape this city’s year are spring trees, warm-season grasses, late-summer ragweed and winter mountain cedar in the west of the region — named here as regional context only, not as today\u2019s measurements.
Plant detail returns here automatically on any day the source data includes it.

Newcastle pollen through the year
The Newcastle 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 Newcastle 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 Newcastle 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 Newcastle, 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.

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