Pollen count Tehran residents check each morning
The Tehran pollen count today is 14 (Low). The main driver is Ragweed, with weed pollen at 18 today. That total sits on a narrow base: weed pollen is 18 while tree pollen is just 0.6 and grass pollen 1. Plant-by-plant detail for Tehran, Iran follows, along with the outlook for the days ahead. 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 Tehran 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.

Tehran allergies today
Tehran allergies today are set by the same reading as the pollen count above: the Total Pollen Index is 14 (Low), driven mainly by Ragweed. When people ask about Tehran allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Tehran.
Allergies in Tehran follow the Iran 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 Tehran 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 Tehran allergy forecast: today reads 14 (Low), and the day-by-day outlook shows whether Tehran 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 Tehran today records is this same combined reading — tree, grass, weed and mold in one index.
The Tehran allergy count today is 14 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Tehran
What is driving Tehran’s pollen today
The shape of today’s 14 (Low) is set by weed pollen at 18 (Low on its own scale) — about 92% of the four category readings added together, 17 points clear of the next category, grass pollen at 1. 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 Iran, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for Tehran, 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 19, never changing band. Today’s 14 sits 1 point above the window’s average of 13 — a moving window, worth reading day by day rather than from the average.
Plants affecting Tehran now
Detailed plant-by-plant readings for Tehran 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 0.6 (Low).
Grass pollen is one of the categories with a non-zero reading today, at 1 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 18 (Low).
In the Global pattern, the plants that shape this city’s year vary with its local climate and vegetation, and no single regional calendar is published for this area — named here as regional context only, not as today\u2019s measurements.

Tehran pollen through the year
Chapter by chapter, the Tehran pollen year runs like this:
- Tree pollen seasons vary with local climate and vegetation, so this page reports the measured readings first and treats any calendar as background only.
- Grass pollen seasons vary with local climate and vegetation, and the measured value outranks any general seasonal expectation.
- Weed pollen seasons vary with local climate and vegetation, and no regional calendar is asserted for this area.
No Iran allergy season guide is published yet, so this page does not single out signature pollens for Tehran — the calendar above is the Global regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Tehran is reported from its modelled readings, not from a regional calendar — no regional calendar is asserted for Iran, so the calendar alone explains little today, and the modelled split above carries the story. No Iran allergy season guide is published yet — this calendar follows the Global regional pattern. See Tehran pollen count rankings and Tehran on the pollen heatmap.
How to read this index
Pollen Atlas reports the Tehran 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 Tehran, Iran 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.
Tehran in today’s national picture
At 14 (Low), Tehran ranks joint 69664th of the 90896 cities Pollen Atlas tracks today — in the middle of the national table. The highest reading in the country today is Serpa, Portugal at 53, and the lowest is Galiakberovo, Russia at 5. 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 Tehran resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Tehran, Iran 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.
