Weather in Puerto Montt in January

Prime time. January is about as good as Puerto Montt gets. Highs average 19.8 °C, lows 10.5 °C, and rain falls on 10 days — nothing in the month is working against you.

January ranks 2 of 12 in Puerto Montt. Only February scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 10 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. 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 January reaches 30 °C. Across the twenty years measured, the hottest January day reached 32.9 °C and the coldest night fell to 5.1 °C, and the wettest single day dropped 51 mm — roughly 78% of the month's rain in one day.

January is moderately variable: 6 mm in the driest year against 228 mm in the wettest, around an average of 65 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.

Wind is light at 2.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 81%, high enough to notice on the warm days without dominating them.

How January sits in the year

Temperatures hold steady either side: 18.2 °C in December, 19.8 here, 20.5 in February. Nothing about the timing within the month matters much.

Daylight in January

January is at or near the longest days of Puerto Montt's year: 14.9 hours of daylight, losing 0.8 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

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

January in Puerto Montt versus nearby

So: January is effectively as good as it gets here — 3 points behind February, which is inside the margin where the weather stops being the deciding factor and price starts being it.
