The numbers on Zurich reveal a city where the Alps shape everything. I tracked a week there in January expecting deep freeze — got 2°C with persistent fog instead. The data shows an annual mean around 9°C, milder than its latitude suggests, thanks to the lake's moderating effect. The foehn wind is the wild card: it can spike temperatures 10°C in hours. June-August averages 19°C with 100mm monthly rain — pack for wet. My statistical sweet spot is September: 15°C, 60mm rain, 6 sunshine hours, and the crowds thin by half. December-February averages 2°C with snow possible but not guaranteed.
