Pollen count Isesaki residents check each morning
The Isesaki pollen count today is 24 (Low). The main driver is Ragweed, with weed pollen at 29 today. Weed pollen leads the split at 29 (Low on its own scale), followed by tree pollen at 11 and grass pollen at 2. Below, the plant detail and the multi-day outlook show whether today is the pattern or the exception. 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 Isesaki 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 Isesaki
What is driving Isesaki’s pollen today
The shape of today’s 24 (Low) is set by weed pollen at 29 (Low on its own scale) — about 69% of the four category readings added together, 18 points clear of the next category, tree pollen at 11. 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 Japan, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for Isesaki, 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 21 to 24, never changing band. Today’s 24 sits 1 point above the window’s average of 23.4 — a steady window, in which one day reads much like the next.

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