July is low for Santiago.
July is mid-winter and the peak of the smog season — Santiago's basin traps cold, polluted air, and authorities sometimes declare 'preemergencia' alerts that restrict cars and wood burning. Days are mild (15°C/59°F) but damp and grey, nights near 4°C/39°F.
The Andes are in peak ski season, and the Chilean winter school holidays (mid-July) send families to Valle Nevado, El Colorado, La Parva, and Portillo — so book ski lodging and transfers ahead for that fortnight. The slopes are the reason to come in July.

Santiago in July — Full Picture
July is mid-winter and the peak of the smog season — Santiago's basin traps cold, polluted air, and authorities sometimes declare 'preemergencia' alerts that restrict cars and wood burning. Days are mild (15°C/59°F) but damp and grey, nights near 4°C/39°F.
The Andes are in peak ski season, and the Chilean winter school holidays (mid-July) send families to Valle Nevado, El Colorado, La Parva, and Portillo — so book ski lodging and transfers ahead for that fortnight. The slopes are the reason to come in July.
In the city, lean into indoor Santiago — the museums, wine bars, and warming food (cazuela, pastel de choclo, a glass of Carmenère). The smog can erase the Andes views that make the city special, so manage expectations on hazy days.
Note: the worst air-quality days are unpleasant for sensitive travelers — check the index, favor higher hotel floors, and plan ski/mountain days (above the smog) on the haziest days in town.
