Pollen count Bo residents check each morning

The Bo pollen count today is 14 (Low). The main driver is Ragweed, with weed pollen at 13 today. Grass pollen is the highest single category in the split at 15 (Low), ahead of weed pollen at 13 and tree pollen at 11. Plant-by-plant detail for Bo, Sierra Leone follows, along with the outlook for the days ahead. Pollen Atlas updated this count on Saturday, November 7, 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 Bo 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.

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

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

What is the Bo pollen count today?

The Bo pollen count today is 14 out of 100 (Low) on the Pollen Atlas Total Pollen Index, driven mainly by Ragweed.

Short answer for anyone searching pollen count today Bo: this page is updated every morning with the day’s modelled reading.

Bo allergies today

Bo 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 Bo allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Bo.

Allergies in Bo follow the Sierra Leone 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 Bo 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 Bo allergy forecast: today reads 14 (Low), and the day-by-day outlook shows whether Bo 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 Bo today records is this same combined reading — tree, grass, weed and mold in one index.

The Bo allergy count today is 14 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Bo

What is driving Bo’s pollen today

The shape of today’s 14 (Low) is set by grass pollen at 15 (Low on its own scale) — about 38% of the four category readings added together, 2 points clear of the next category, weed pollen at 13. 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 is a modelled reading, reported as modelled — no regional calendar is asserted for Sierra Leone, and the modelled value outranks any general seasonal expectation.

Plant-level detail is not in today’s feed for Bo, 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 14, never changing band. Today’s 14 sits 2 points above the window’s average of 12 — a steady window, in which one day reads much like the next.

Plants affecting Bo now

Detailed plant-by-plant readings for Bo 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 11 (Low).

Grass pollen is one of the categories with a non-zero reading today, at 15 (Low).

Weed pollen is one of the categories with a non-zero reading today, at 13 (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.

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

Bo pollen through the year

Chapter by chapter, the Bo 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 Sierra Leone allergy season guide is published yet, so this page does not single out signature pollens for Bo — the calendar above is the Global regional pattern, and the plant detail on this page names what today’s feed actually records.

November in Bo is reported from its modelled readings, not from a regional calendar — no regional calendar is asserted for Sierra Leone, so the calendar alone explains little today, and the modelled split above carries the story. No Sierra Leone allergy season guide is published yet — this calendar follows the Global regional pattern. See Bo pollen count rankings and Bo on the pollen heatmap.

How to read this index

Pollen Atlas reports the Bo 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 Bo, Sierra Leone 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.

Bo in today’s national picture

At 14 (Low), Bo ranks joint 71898th of the 90896 cities Pollen Atlas tracks today — in the middle of the national table. The highest reading in the country today is Beja, Portugal at 52, and the lowest is Los Ángeles de San Rafael, Spain at 5. The whole table spans 47 points today — a wide-open day, when the top and bottom of the table are effectively in different seasons.

Around Bo: Kenema, Sierra Leone (61 km away) reads 14 (Low); Freetown, Sierra Leone (175 km away) reads 16 (Low); Monrovia, Liberia (212 km away) reads 19 (Low). Bo reads exactly level with its nearest tracked neighbour today. Across Sierra Leone’s 3 tracked cities, today runs from 14 in Kenema to 16 in Freetown.

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