Also exploring
New York
USA
A city that never fully quiets — but its personality shifts dramatically by season, from sweltering humid summers to crisp autumn perfection to blizzard-prone winters.
Rio de Janeiro
Brazil
A Southern Hemisphere city where summer (December–March) brings Carnival and 264mm of rain simultaneously, and the real sweet spot is the dry Southern winter — June to September — when most travellers don't think to come.
Mexico City
Mexico
A highland metropolis at 2,240 metres where the altitude tempers the heat to perpetual spring in the dry months, Día de Muertos transforms Mixquic and Azcapotzalco into one of the world's great ceremonies, and the October–April dry season gives the clearest conditions for exploring what is genuinely one of the planet's finest food, museum, and architecture cities.
