What is Ushuaia’s weather like in December?<\/strong> December brings the beginning of the Southern Hemisphere summer, long daylight hours and plenty of opportunities to explore Tierra del Fuego. However, summer at the End of the World is still cool, windy and changeable. You should pack for several types of weather, sometimes on the same day.<\/p>\n

Does it rain in Ushuaia in December?<\/h2>\n

Yes. Light rain, drizzle and periods of cloud are possible throughout the year. The monthly precipitation figure is a long-term average: it does not mean it will rain every day of your holiday. Waterproof outerwear and a flexible schedule are much more useful than trying to predict the weather months in advance.<\/p>\n

Can you see snow in December?<\/h2>\n

Snow in the city is relatively uncommon at this time of year, although occasional events are possible. Mountain trails and higher elevations may still have patches of snow or winter-like conditions. For skiing and a classic winter landscape, June to September is generally a better starting point when choosing your dates. See our guide to when it snows in Ushuaia<\/a>.<\/p>\n

How many hours of daylight does Ushuaia get in December?<\/h2>\n

A major benefit of visiting in December is the exceptionally long day. Near the December 21 summer solstice<\/strong>, Ushuaia receives approximately 17 hours and 20 minutes of daylight<\/strong>. Sunrise is close to 4:50 a.m. and sunset around 10:10 p.m., depending on the date and year. This gives you extra time for sightseeing, although daylight alone does not make a hiking route safe.<\/p>\n

Is it windy in December?<\/h2>\n

Wind is a defining feature of the region. A sheltered street in town may feel comfortable while an exposed viewpoint or a Beagle Channel cruise feels much colder. Wear a windproof jacket, and remember that boat operators may change their sailing plans because of weather or sea conditions.<\/p>\n
