Climate Chart of Puerto Williams, Chile

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

Climate overview

Temperature

Monthly mean temperatures peak in January / February at 9.4 °C, while the lowest monthly mean is recorded in July at 0.2 °C. The unweighted mean of the monthly means is 5.0 °C. These figures describe typical monthly averages rather than daytime highs; they cannot tell visitors exactly how warm or cold an individual day will feel.

Rain

Mean daily rainfall is highest in January at 3.15 mm/day and lowest in June at 0.66 mm/day. The unweighted mean across monthly means is 1.69 mm/day. These are daily average amounts, not monthly totals, and the lower average does not guarantee rain-free days or indicate how frequently rain occurs; keeping rain protection available is therefore useful when planning outdoor time.

Snow

Mean daily snowfall is highest in August at 8.20 mm/day and lowest in February at 0.61 mm/day; the unweighted mean across monthly means is 3.93 mm/day. These averages record snowfall amounts, not the number of snowy days, snow depth, lasting snow cover, or conditions for skiing.

Sunshine

Average daily sunshine reaches its highest monthly mean in December at 10.67 hours/day, and its lowest in June at 2.82 hours/day. The unweighted mean of the monthly figures is 6.95 hours/day. Sunshine duration can help with planning outdoor sightseeing, but it is not the same as day length and does not guarantee clear skies throughout a day.

Best Travel Time Guide for Puerto Williams, Chile: Ideal Seasons and Weather Insights

For visitors prioritising lower average rainfall, June is the criterion-based option, with mean daily rainfall of 0.66 mm/day; this does not promise dry weather or show how often rain falls. In contrast, mean daily rainfall is highest in January at 3.15 mm/day, so rain protection is sensible when planning outdoor activities, whichever dates you choose. Those seeking cooler monthly averages can look to July, when the monthly mean temperature is 0.2 °C. For daylight outdoor planning, mean daily sunshine is highest in December at 10.67 hours/day and lowest in June at 2.82 hours/day; these are separate considerations, not a combined ranking of the best time to visit. The mean daily snowfall reaches its highest monthly figure in August at 8.20 mm/day. This can inform preparation, but the average alone does not establish how many days have snow, whether snow will remain on the ground, or what conditions visitors will encounter.
