Pollen count Hamilton residents check each morning
The Hamilton pollen count today is 24 (Moderate). The main driver is Ragweed, with weed pollen at 24 today. That total sits on a narrow base: weed pollen is 24 while tree pollen is just 5 and grass pollen 16. Plant-by-plant detail for Hamilton, Bermuda follows, along with the outlook for the days ahead. Pollen Atlas updated this count on Saturday, November 14, 2026.
A Moderate band means the Total Pollen Index sits in the middle of the 0–100 scale — neither a quiet day nor a peak day. On moderate days the split usually explains the total: one or two categories do most of the work while the others stay low. The Hamilton split above shows exactly which categories those are today, and the forecast below shows whether the moderate reading is a plateau or a step toward a higher band.
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 Hamilton residents check each morning, built from the day’s tree, grass and weed readings.

When people ask about Hamilton allergies, this is the number that answers them — one daily index built from today’s tree, grass and weed readings for Hamilton.
Allergies in Hamilton follow the Bermuda 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 Hamilton 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 Hamilton allergy forecast: today reads 24 (Moderate), and the day-by-day outlook shows whether Hamilton 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 Hamilton today records is this same combined reading — tree, grass and weed in one index.
The Hamilton allergy count today is 24 (Moderate) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Hamilton
What is driving Hamilton’s pollen today
The shape of today’s 24 (Moderate) is set by weed pollen at 24 (Moderate on its own scale) — about 53% of the four category readings added together, 8 points clear of the next category, grass pollen at 16. 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 Bermuda, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for Hamilton, 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 24 to 34, never changing band. Today’s 24 sits 6 points below the window’s average of 30 — a moving window, worth reading day by day rather than from the average.
Plants affecting Hamilton now
Detailed plant-by-plant readings for Hamilton 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 5 (Low).
Grass pollen is one of the categories with a non-zero reading today, at 16 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 24 (Moderate).
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.

Hamilton pollen through the year
Chapter by chapter, the Hamilton 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 Bermuda allergy season guide is published yet, so this page does not single out signature pollens for Hamilton — the calendar above is the Global regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Hamilton is reported from its modelled readings, not from a regional calendar — no regional calendar is asserted for Bermuda, so the calendar alone explains little today, and the modelled split above carries the story. No Bermuda allergy season guide is published yet — this calendar follows the Global regional pattern. See Hamilton pollen count rankings and Hamilton on the pollen heatmap.
How to read this index
Pollen Atlas reports the Hamilton 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 Hamilton, Bermuda 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.

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Hamilton resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Hamilton, Bermuda can test whether tree, grass or weed is the category that matters for you — the three readings at the top of this page are the starting point for that conversation.
