Weather in Puerto Montt in April
Chile · 20-year averages, April
Shoulder season. April sits in between. You will get good days and you will lose some. You should expect rain on 15 days of the month, which is more days wet than dry.
April ranks 6 of 12 in Puerto Montt: past the worst of the year but short of February, which is the month to book if the dates are open.
Rain on 15 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 15.6 °C days and 8.1 °C nights; the spread matters more here than any single number.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest April day reached 24.5 °C and the coldest night fell to 2.2 °C, and the wettest single day dropped 96 mm — roughly 85% of the month's rain in one day.
April is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest April on record still delivered 235 mm against 57 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 113 mm average is a reasonable planning figure, not a promise.
Wind is light at 2.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 87%, high enough to notice on the warm days without dominating them.
How April sits in the year
The month is on the way down: 3 °C cooler than March, with May dropping another 2.6 °C. The first week and the last are not the same trip.
Daylight in April
11 hours of daylight, losing 1.3 hours across the month. That is between Puerto Montt's extremes of 15.1 and 9.2 hours, so days are long enough not to constrain the plan.
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
Shoulder. The value months — prices ease off and you get the place closer to itself.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
April 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 April — 12.4 °C warmer, 12 days less rain. Córdoba is a better bet in April — 10.4 °C warmer, 8 days less rain.
So: April is a compromise. February is 26 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.
