Pollen count Arusha residents check each morning
The Arusha pollen count today is 21 (Low). The main driver is Ragweed, with weed pollen at 21 today. The full split is tree pollen 18, grass pollen 20, weed pollen 21. 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 Thursday, November 5, 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 Arusha 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.

This is the pollen count Arusha residents check each morning, built from the day’s tree, grass, weed and mold readings.

When people ask about Arusha allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Arusha.
Allergies in Arusha follow the Tanzania calendar set out below — the chapters, the plants behind them, and the 5-day forecast on this page show whether today is typical for the season or an exception to it. If you are checking allergies today in Arusha before heading outdoors, the split at the top of this page is the part to read: it shows which pollen is doing the work today, not just how high the total sits.
Read the five-day table on this page as the Arusha allergy forecast: today reads 21 (Low), and the day-by-day outlook shows whether Arusha allergies are set to ease or build across the week — the days to plan outdoor time around are the ones where the index steps down, not just today.
In practice, the allergy count Arusha today records is this same combined reading — tree, grass, weed and mold in one index.
The Arusha allergy count today is 21 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Arusha
What is driving Arusha’s pollen today
The shape of today’s 21 (Low) is set by weed pollen at 21 (Low on its own scale) — about 36% of the four category readings added together, 1 points clear of the next category, grass 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 a modelled reading, reported as modelled — no regional calendar is asserted for Tanzania, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for Arusha, so the drivers have to be read from the category split above — it shows how much of today’s total each category is actually carrying, and plant detail returns here automatically on any day the feed includes it.
Across the five-day window the Total Pollen Index runs from 9 to 21, never changing band. Today’s 21 sits 8 points above the window’s average of 12.6 — a moving window, worth reading day by day rather than from the average.
Plants affecting Arusha now
Detailed plant-by-plant readings for Arusha 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.

Grass pollen is one of the categories with a non-zero reading today, at 20 (Low).

Arusha pollen through the year
The Arusha pollen year runs in chapters, set by the Global pattern and the Tanzania calendar. Trees come first: tree pollen seasons vary with local climate and vegetation, so this page reports the measured readings first and treats any calendar as background only. Grasses take the middle of the year: grass pollen seasons vary with local climate and vegetation, and the measured value outranks any general seasonal expectation. Weeds close it out: weed pollen seasons vary with local climate and vegetation, and no regional calendar is asserted for this area.
No Tanzania allergy season guide is published yet, so this page does not single out signature pollens for Arusha — the calendar above is the Global regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Arusha is reported from its modelled readings, not from a regional calendar — no regional calendar is asserted for Tanzania, so the calendar alone explains little today, and the modelled split above carries the story. No Tanzania allergy season guide is published yet — this calendar follows the Global regional pattern. See Arusha pollen count rankings and Arusha on the pollen heatmap.
How to read this index
Pollen Atlas reports the Arusha 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 Arusha, Tanzania 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.
Arusha in today’s national picture

The whole table spans 48 points today — a wide-open day, when the top and bottom of the table are effectively in different seasons.

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