Pollen count Dehiwala-Mount Lavinia residents check each morning
The Dehiwala-Mount Lavinia pollen count today is 10 (Low). The main driver is Ragweed, with weed pollen at 10 today. Grass pollen is the highest single category in the split at 10 (Low), ahead of weed pollen at 10 and tree pollen at 8. 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 Dehiwala-Mount Lavinia 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 Dehiwala-Mount Lavinia
What is driving Dehiwala-Mount Lavinia’s pollen today
The shape of today’s 10 (Low) is set by grass pollen at 10 (Low on its own scale) — about 36% of the four category readings added together, level with weed pollen at 10. 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 Sri Lanka, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for Dehiwala-Mount Lavinia, 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 10 to 16, never changing band. Today’s 10 sits 1 point below the window’s average of 11.4 — a moving window, worth reading day by day rather than from the average.

Dehiwala-Mount Lavinia pollen through the year

Weeds close it out: weed pollen seasons vary with local climate and vegetation, and no regional calendar is asserted for this area.

How to read this index
Pollen Atlas reports the Dehiwala-Mount Lavinia 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 Dehiwala-Mount Lavinia, Sri Lanka 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.
