Weather in Santiago in June

Prime time. June is about as good as Santiago gets. Highs average 20.2 °C, lows 8.3 °C, and rain falls on 6 days — nothing in the month is working against you.

June ranks 6 of 12 in Santiago: past the worst of the year but short of September, which is the month to book if the dates are open.

Rain falls on only 6 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average June reaches 30 °C. Across the twenty years measured, the hottest June day reached 30.6 °C and the coldest night fell to -3 °C, and the wettest single day dropped 66 mm — roughly 105% of the month's rain in one day.

June is moderately variable: 1 mm in the driest year against 171 mm in the wettest, around an average of 63 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind is light at 5.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 49%.

How June sits in the year

Temperatures hold steady either side: 23.7 °C in May, 20.2 here, 19.4 in July. Nothing about the timing within the month matters much.

Daylight in June

June sits at the dark end of Santiago's year — 9.9 hours of daylight against 14.3 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

An inland climate

With no coast nearby, the year swings a fair way — 26.3 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

June in Santiago versus nearby

If Santiago is one option among several, the nearby comparison is worth making. Córdoba is a better bet in June — within a degree on temperature, 5 days less rain. San Miguel de Tucumán is close enough to be a coin toss — within a degree on temperature, 3 days less rain.

So: June works, with September the better month by 7 points if the dates can move. If they cannot, nothing here should stop you booking.
