Local date, timezone, and clock behavior

Planning windows for Maipú use the IANA timezone America/Santiago. On this page's publication date, the local date is Sunday, July 19, 2026 and the UTC offset is UTC-04:00.

The January and July reference offsets differ (UTC-03:00 and UTC-04:00). That means the timezone database applies an offset change during the year; AirAgora converts absolute provider timestamps rather than adding hours to a displayed clock.

Which provider air-quality scale is shown for Maipú?

AirAgora displays OpenWeather’s official air-pollution scale from 1 to 5. It is not labeled European AQI, U.S. AQI, or a local regulatory index.

The provider category is preserved for display. AirAgora derives continuous internal severity from documented pollutant concentration bands for ranking; that internal value is not a synthetic AQI or a promise of safety.

Modeled forecast and local limits

Maipú uses the OpenWeather modeled air-pollution forecast. The selected coordinate represents provider forecast data, not a street-level monitor, indoor measurement, or personal exposure estimate.

OpenWeather 1–5

The official provider category stays visible and is not relabeled as a regulatory AQI.

Pollutant severity

Internal scoring comes from documented concentration bands and is never presented as a synthetic AQI.

How to use the Maipú planner

Start with the live current-category teaser, choose the activity, then use the email reveal for a complete hourly comparison. AirAgora evaluates complete two-hour windows starting between 06:00 and 22:00 local time. It gives 70% of the score to mean severity and 30% to the worst hour, keeps an earlier window when scores are materially tied, and avoids naming a winner when the difference is too small.%!(EXTRA string=Maipú)

If every practical period remains in a poor category, the result is described as the least polluted available window rather than as good or safe. Missing hours, provider errors, and stale data remain visible instead of being filled with invented values.
