Climate Chart of Ushuaia, Argentina

Climate overview

Temperature

The warmest monthly mean is 9.3 °C in February, while the coolest is 0.1 °C in July. Their contrast describes the span between monthly averages; temperatures on individual days can vary and are not represented by these means. Across the calendar months, the unweighted mean of monthly mean temperatures is 4.8 °C. It is a summary of monthly means rather than a day-weighted annual average, and should not be read as a typical daytime maximum.

Sunshine

Mean daily sunshine is highest at 11.00 hours/day in December and lowest at 2.94 hours/day in June. These figures describe average sunshine duration, not daylight length, and do not promise the same conditions on each day. The unweighted mean across the monthly mean sunshine durations is 7.02 hours/day per day. It provides an overall reference for the year, but is not a forecast of clear skies for a particular visit.

Rain

Mean daily rainfall reaches its monthly high of 3.51 mm/day in January and its low of 0.73 mm/day in June. These are daily average amounts, not monthly totals; the lower average does not guarantee rain-free days or indicate how often rain occurs. The unweighted mean of the monthly mean daily rainfall figures is 1.95 mm/day. It offers a broad year-round reference, while actual daily conditions may differ from that summary.

Snow

Mean daily snowfall has a monthly high of 12.50 mm/day in August and a low of 1.13 mm/day in January. These are average daily amounts, not monthly totals, and they do not establish how many days have snow, snow depth, snow cover or skiing conditions. The unweighted mean of the monthly mean daily snowfall figures is 6.57 mm/day. Treat it as an amount-based summary only; it cannot describe the timing or persistence of snow on the ground.
