Pollen count San Lorenzo zona urbana residents check each morning

The San Lorenzo zona urbana pollen count today is 8 (Low). The main driver is Ragweed, with weed pollen at 7 today. Tree pollen is the highest single category in the split at 8 (Low), ahead of weed pollen at 7 and grass pollen at 6. 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 tree pollen, reading noticeably higher than the rest, which is why the split is printed on every San Lorenzo zona urbana 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 San Lorenzo zona urbana

What is driving San Lorenzo zona urbana’s pollen today

The shape of today’s 8 (Low) is set by tree pollen at 8 (Low on its own scale) — about 38% of the four category readings added together, 1 points clear of the next category, weed pollen at 7. Tree readings are the fastest-moving of the four in their season, because species pollinate in sequence — a tree-led total can change character within a week. Tree pollen leading in November runs against the usual calendar — the PR tree chapter runs February to May — so today’s lead is the model outranking the pattern, and this page reports the modelled reading first.

Plant-level detail is not in today’s feed for San Lorenzo zona urbana, 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 7 to 17, never changing band. Today’s 8 sits 1 point below the window’s average of 9.2 — a moving window, worth reading day by day rather than from the average.

San Lorenzo zona urbana pollen through the year

The San Lorenzo zona urbana pollen year runs in chapters, set by the Southeast pattern and the PR calendar. Trees come first: trees can start as early as February and peak in April.

How to read this index

Pollen Atlas reports the San Lorenzo zona urbana 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 San Lorenzo zona urbana, PR 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.
