Definition: a city is “mild in September” when its monthly mean temperature is between 15 and 26 °C (10-year mean). These are climatological means, not a weather forecast — check a live forecast before travelling. Source: Open-Meteo Historical Weather API (CC BY 4.0, 2015–2024). Grouped by continent, ordered by temperature within each group — a filter tool, not a ranking or liveability judgement.
