Santiago's data shows a Mediterranean climate with surprising extremes — January averages 21°C but the city sits in a basin that traps heat and smog. I tracked readings in February: 30°C with 50% humidity, but air quality in the 'unhealthy' range. The numbers favor September-November: 15-19°C, low rain, clearer air. December-March is hot and dry with smog issues. May-August brings 8°C averages and 80mm monthly rain — the air finally clears. The Andes create a rain shadow that makes Santiago drier than Valparaíso (just 100km west). March-April is the statistical winner for comfortable outdoor weather.
