Climate Chart of Punta Arenas, Chile

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

Monthly mean temperature reaches its highest point in February, at 9.9 °C; this is a monthly average, not a typical daytime high. At the cooler end, July has a monthly mean of 1.5 °C. The unweighted mean of the monthly means is 5.9 °C, a summary across calendar months rather than a day-weighted annual average. These averages describe the broad temperature pattern, not daily highs, overnight lows or the conditions visitors will meet on a particular date.

Rain

Mean daily rainfall is highest in March, at 2.71 mm/day, and lowest in September, at 1.04 mm/day. The figures are daily means for those months, not monthly accumulation totals, and the unweighted mean of the monthly means is 1.86 mm/day. The lower monthly mean does not guarantee dry days or show how often rain occurs, so these values are best used as broad guidance rather than a day-by-day forecast.

Sunshine

Mean daily sunshine duration peaks in December at 10.56 hours/day, while its lowest monthly mean is June at 3.44 hours/day. Across the calendar-month means, the unweighted mean is 7.05 hours/day. These are averages of sunshine duration, not measures of day length, and they cannot guarantee clear skies on a planned outing.

Snow

Mean daily snowfall reaches its highest monthly average in August, at 7.39 mm/day; the lowest is in February, at 0.18 mm/day. The unweighted mean of monthly means is 2.88 mm/day. These are daily average amounts, not monthly totals, and they do not establish how many days receive snow, snow depth or whether snow cover persists.

Best Travel Time Guide for Punta Arenas, Chile: Ideal Seasons and Weather Insights

For visitors prioritising lower average rainfall, September is the conditional option: its mean daily rainfall is 1.04 mm/day. That is not a promise of dry weather or a measure of rain frequency, so flexible plans and rain-ready clothing remain sensible; March has the highest monthly mean, at 2.71 mm/day, and is a useful reference when preparing for rain. Those prioritising cooler monthly averages can look to July, when the mean temperature is 1.5 °C. For daylight outdoor planning, mean daily sunshine is lowest in June at 3.44 hours/day and highest in December at 10.56 hours/day; sunshine duration is not day length and does not ensure clear conditions. These are separate criteria, not a combined best-time ranking. Snowfall averages also provide context for packing, but not a prediction of conditions on a particular day: the highest mean daily snowfall is August at 7.39 mm/day. This amount does not reveal the number of snowy days, snow depth or snow cover, so it cannot by itself establish what outdoor activities will be feasible.
