Santiago in April — Full Picture
April is a lovely, mellow autumn month — mild days around 23°C/73°F, cool nights near 8°C/46°F, and the return of the first proper rains after the dry summer. Parks like Parque Forestal and the wine valleys take on autumn color.
It's a comfortable, lower-crowd time to do the full city program and a relaxed wine-country trip (the late harvest lingers in cooler valleys). The light is soft and golden, good for photography on Cerro San Cristóbal and along the Mapocho.
The day-night temperature swing grows, so layering matters — warm afternoons can turn chilly by evening. A packable rain jacket is worth having now, though rain is still occasional rather than constant.
Note: April sits in the shoulder-season sweet spot with March — pleasant weather, autumn scenery, and better value than summer, before the winter cool and smog arrive in May.
What to Wear & What to Pack
Autumn — mild, with the first real rains. Highs near 23°C/73°F, nights around 8°C/46°F. Layers, a light sweater, and a packable rain jacket. A bigger day-night swing, so dress in layers.
