Mexico City's altitude (2,240m) is the packing variable everyone forgets. I packed for 25°C days and shivered through 12°C nights — the swing is real. Layering is non-negotiable; bring a fleece even in May. The dry season (November-April) is the sweet window: 22°C, low rain, low humidity. Skip May-June when heat plus dust plus ozone make breathing uncomfortable. July-September is rainy season — spectacular afternoon thunderstorms but plan indoor mornings. Sunscreen is essential at altitude even on cloudy days. And drink water constantly; the thin air dehydrates you faster than you'd expect.
