Best time to visit Santiago
Chile · 20-year averages
September is the best month in Santiago, scoring 95 out of 100, with January the weakest at 67. The 28-point spread means timing is worth planning around without being decisive. The good window runs April to October — 7 months within ten points of the best.
January is the warmest month at 33.7 °C and July the coolest at 19.4 °C — a 14.3 °C spread across the year. 145 days a year top 30 °C, more than a third of the calendar, so heat is the baseline here rather than a season.
Rain is spread evenly through the year — between 2 and 6 wet days in every month — so there is no dry season to aim for and no wet one to dodge. Whatever you plan, the odds of rain are much the same.
Daylight runs from 9.9 hours in winter to 14.3 in summer, enough to notice on a sightseeing itinerary.
The three strongest months are September, October, April. The one to think twice about is January. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
