Valparaíso in September

October through March gives you the best weather — warm, dry days perfect for wandering the hills and outdoor dining. December and January are peak summer, so expect crowds and higher prices, especially around New Year's when Santiago residents flood the coast. But here's what locals know: April and May offer sweet spots with fewer tourists and still-pleasant weather. The autumn light makes the colored houses pop even more, and you'll actually get tables at the good restaurants without reservations. Winter (June-September) brings rain and fog, but also a different kind of beauty. The city feels more intimate, locals reclaim their neighborhoods, and you'll find better deals on accommodation. Just pack layers — coastal weather changes fast, and those hillside winds cut right through light jackets.
