Pollen count San José de Mayo residents check each morning
The San José de Mayo pollen count today is 75 (High). 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 1, grass pollen 75, weed pollen 30. Plant-by-plant detail for San José de Mayo, Uruguay follows, along with the outlook for the days ahead. Pollen Atlas updated this count on Saturday, November 14, 2026.
A High band means the Total Pollen Index is in the upper part of the 0–100 scale, a position it only reaches when at least one pollen category is itself reading high. The split above identifies that category for San José de Mayo today. High-band days are also the days when the day-to-day change matters most, so the forecast section below — not the single headline number — is the part of this page to compare against tomorrow’s reading.
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.

Pollen by type in San José de Mayo
What is driving San José de Mayo’s pollen today
The shape of today’s 75 (High) is set by grass pollen at 75 (High on its own scale) — about 71% of the four category readings added together, 45 points clear of the next category, weed pollen at 30. 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 Uruguay, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for San José de Mayo, 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 35 to 75, changing band 1 time. Today’s 75 sits 16 points above the window’s average of 59.2 — a wide-open window, in which the day matters more than the average.

How to read this index
Pollen Atlas reports the San José de Mayo 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.
