Weather in Puerto Montt in March
Chile · 20-year averages, March
A good month. March is a solid month to be in Puerto Montt. Highs average 18.6 °C, lows 9.7 °C, and rain falls on 12 days — nothing in the month is working against you.
March ranks 4 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 12 days, 3 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 March reaches 30 °C. Across the twenty years measured, the hottest March day reached 29.6 °C and the coldest night fell to 5 °C, and the wettest single day dropped 46 mm — roughly 53% of the month's rain in one day.
March is moderately variable: 24 mm in the driest year against 181 mm in the wettest, around an average of 86 mm. Roughly two Marchs 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 83%, high enough to notice on the warm days without dominating them.
How March sits in the year
The month is on the way down: 1.9 °C cooler than February, with April dropping another 3 °C. The first week and the last are not the same trip.
Daylight in March
12.4 hours of daylight, losing 1.4 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
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.
March in Puerto Montt versus nearby
If Puerto Montt is one option among several, the nearby comparison is worth making. Santiago is close enough to be a coin toss — 13 °C warmer, 9 days less rain. Córdoba is close enough to be a coin toss — 10.7 °C warmer, 2 days less rain.
So: March works, with February the better month by 12 points if the dates can move. If they cannot, nothing here should stop you booking.
