Pollen count Castro residents check each morning
The Castro pollen count today is 71 (High). No single plant stands out in today’s readings; the Grass category is the one the index is led by. Tree pollen is the highest single category in the split at 71 (High), ahead of grass pollen at 49 and weed pollen at 29. 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 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 Castro 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.
To see whether today’s pollen level holds, check the 5-day Castro pollen forecast below — it is currently mixed, with Sunday the highest day in the window.
This is the pollen count Castro residents check each morning, built from the day’s tree, grass and weed readings.

Pollen by type in Castro
What is driving Castro’s pollen today
The shape of today’s 71 (High) is set by tree pollen at 71 (High on its own scale) — about 48% of the four category readings added together, 22 points clear of the next category, grass pollen at 49. 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 is a modelled reading, reported as modelled — no regional calendar is asserted for Chile, and the modelled value outranks any general seasonal expectation.
Plant-level detail is not in today’s feed for Castro, 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 59 to 73, never changing band. Today’s 71 sits 5 points above the window’s average of 66 — a moving window, worth reading day by day rather than from the average.

Castro pollen through the year
The Castro pollen year runs in chapters, set by the Global pattern and the Chile calendar. Trees come first: tree pollen seasons vary with local climate and vegetation, so this page reports the measured readings first and treats any calendar as background only. Grasses take the middle of the year: grass pollen seasons vary with local climate and vegetation, and the measured value outranks any general seasonal expectation. Weeds close it out: weed pollen seasons vary with local climate and vegetation, and no regional calendar is asserted for this area.
No Chile allergy season guide is published yet, so this page does not single out signature pollens for Castro — the calendar above is the Global regional pattern, and the plant detail on this page names what today’s feed actually records.
November in Castro is reported from its modelled readings, not from a regional calendar — no regional calendar is asserted for Chile, so the calendar alone explains little today, and the modelled split above carries the story. No Chile allergy season guide is published yet — this calendar follows the Global regional pattern. See Castro pollen count rankings and Castro on the pollen heatmap.
How to read this index
Pollen Atlas reports the Castro 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.

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Castro resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Castro, Chile 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.
