Weather in Puerto Montt in June

A hard month. June is a hard month in Puerto Montt, and worth planning around. You should expect rain on 20 days of the month, which is more days wet than dry.

June ranks 11 of 12 — near the bottom of Puerto Montt's year. February is the month that works, and the swing between the two is 51 points, which is a different holiday rather than a slightly better one.

Rain on 20 of the month's 30 days, 7 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Layers, and a genuinely waterproof outer — at 10.5 °C the difference between a good day and a miserable one is entirely down to what you are wearing.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 5.1 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 16.1 °C and the coldest night fell to -0.9 °C, and the wettest single day dropped 50 mm — roughly 28% of the month's rain in one day.

June is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest June on record still delivered 308 mm against 28 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 181 mm average is a reasonable planning figure, not a promise.

Wind is light at 3.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 92%, which at 10.5 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How June sits in the year

Temperatures hold steady either side: 13 °C in May, 10.5 here, 9.9 in July. Nothing about the timing within the month matters much.

Daylight in June

June sits at the dark end of Puerto Montt's year — 9.2 hours of daylight against 15.1 at midsummer, holding steady all month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

An inland climate

Despite being inland, the year stays fairly even: 15.9 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

June in Puerto Montt versus nearby

If Puerto Montt is one option among several, the nearby comparison is worth making. Santiago is a better bet in June — 9.7 °C warmer, 14 days less rain. Córdoba is a better bet in June — 10.2 °C warmer, 19 days less rain.

So: June is a compromise. February is 49 points better and is what Puerto Montt is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
