Pollen count Old Harbor residents check each morning

The Old Harbor pollen count today is 31 (Low). No single plant stands out in today’s readings; the Grass category is the one the index is led by. The full split is tree pollen 0.6, grass pollen 40, weed pollen 0.6. 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 grass pollen, reading noticeably higher than the rest, which is why the split is printed on every Old Harbor page.

Outside its main late-spring and early-summer window, grass pollen usually appears as a small background value rather than the driver of the total. A low grass reading alongside a higher weed or mold value is a typical off-peak pattern. Grass should be read from its own value on this page, not assumed from the calendar: the index reports today’s modelled value, and the modelled value outranks any general seasonal expectation.

To see whether today’s pollen level holds, check the 5-day Old Harbor pollen forecast below — it is currently mixed, with Tuesday the highest day in the window.

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

Pollen by type in Old Harbor

What is driving Old Harbor’s pollen today

The shape of today’s 31 (Low) is set by grass pollen at 40 (Low on its own scale) — about 97% of the four category readings added together, 39.4 points clear of the next category, tree pollen at 0.6. Grass-led totals tend to hold a level for days at a time rather than spike and clear, because grasses pollinate over an extended period. Grass pollen leading in November runs against the usual calendar — the Alaska grass chapter runs July to July — so today’s lead is the model outranking the pattern, and this page reports the modelled reading first.

Plant-level detail is not in today’s feed for Old Harbor, so the drivers have to be read from the category split above. The Alaska guide’s account of Alaska names paper birch, dominating a compressed May peak, with alder and cottonwood opening for it — 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 34, changing band 1 time. Today’s 31 sits 9 points above the window’s average of 21.6 — a moving window, worth reading day by day rather than from the average.

Plants affecting Old Harbor now

Detailed plant-by-plant readings for Old Harbor 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 40 (Low).

Weed pollen is one of the categories with a non-zero reading today, at 0.6 (Low).

In the Alaska pattern, the plants that typically shape this city’s year are paper birch above all, with alder and cottonwood opening for it, spruce following, and a brief July grass peak — named here as regional context only, not as today\u2019s measurements.

Plant detail returns here automatically on any day the source data includes it.

Old Harbor pollen through the year

The Old Harbor pollen year runs in chapters, set by its own pattern and the Alaska calendar. Trees come first: cottonwood, poplar and aspen stir in late April or early May, birch and alder peak in mid-May, and spruce carries late May into June. Grasses take the middle of the year: grass owns July alone, a brief peak after the tree burst. Weeds close it out: there is no ragweed chapter at these latitudes — ragweed is essentially absent, and the late window belongs to mold. Mold closes the show into September, rising from decaying boreal vegetation — and in the Southeast panhandle it is the persistent presence long after the pollen calendar closes.

The Alaska allergy season guide names paper birch, dominating a compressed May peak, with alder and cottonwood opening for it. University of Alaska Fairbanks researchers have recorded birch counts above 4,500 grains per cubic meter on the Interior’s biggest days. Ragweed is essentially absent at these latitudes, so the season’s final act belongs to mold rising from decaying boreal vegetation through late summer.

November falls between the main chapters of the Alaska pollen year — the tail of one and the approach of the next — so the calendar alone explains little today, and the modelled split above carries the story. Between them, the three chapters cover 6 months of the Alaska year, April to September — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Alaska allergy season guide.

How to read this index

Pollen Atlas reports the Old Harbor 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 whatever the month. 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.
