Pollen count Port of Spain residents check each morning
The Port of Spain pollen count today is 40 (Moderate). The main driver is Ragweed, with weed pollen at 40 today. Weed pollen leads the split at 40 (Moderate on its own scale), followed by grass pollen at 37 and tree pollen at 14. Below, the plant detail and the multi-day outlook show whether today is the pattern or the exception. 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 Port of Spain 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.

Pollen by type in Port of Spain
What is driving Port of Spain’s pollen today
The shape of today’s 40 (Moderate) is set by weed pollen at 40 (Moderate on its own scale) — about 44% of the four category readings added together, 3 points clear of the next category, grass pollen at 37. 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 Trinidad and Tobago, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for Port of Spain, 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 33 to 40, never changing band. Today’s 40 sits 1 point above the window’s average of 38.6 — a moving window, worth reading day by day rather than from the average.

How to read this index
Pollen Atlas reports the Port of Spain 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 Port of Spain, Trinidad and Tobago 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.
