Through Archipelago, South America and Strait

Cape Horn was identified by mariners and first rounded in 1616 by the Dutchmen Willem Schouten and Jacob Le Maire, who named it Kaap Hoorn (pronunciation) after the city of Hoorn in the Netherlands. For decades, Cape Horn was a major milestone on the clipper route, by which sailing ships carried trade around the world. The waters around Cape Horn are particularly hazardous, owing to strong winds, large waves, strong currents and icebergs.

The need for boats and ships to round Cape Horn was greatly reduced by the opening of the Panama Canal in August 1914. Sailing around Cape Horn is still widely regarded as one of the major challenges in yachting. Thus, a few recreational sailors continue to sail this route, sometimes as part of a circumnavigation of the globe. Almost all of these choose routes through the channels to the north of the Cape (many take a detour through the islands and anchor to wait for fair weather to visit Horn Island, or sail around it to replicate a rounding of this historic point). Several prominent ocean yacht races, notably the Volvo Ocean Race, Velux 5 Oceans Race, and the solo Vendée Globe and Golden Globe Race, sail around the world via the Horn. Speed records for round-the-world sailing are recognized for following this route.

Geography and ecology

Cape Horn is located on Hornos Island in the Hermite Islands group, at the southern end of the Tierra del Fuego archipelago. It marks the northern edge of the Drake Passage, the strait between South America and Antarctica. It is located in Cabo de Hornos National Park, Core of the Cape Horn Biosphere Reserve.

The cape lies within Chilean territorial waters, and the Chilean Navy maintains a station on Horn Island, consisting of a residence, utility building, chapel, and lighthouse, as well as the southern neighborhood of the Diego Ramírez Islands and the waters of the Diego Ramirez Islands & Drake Passage National Park . A short distance from the main station is a memorial, including a large sculpture made by Chilean sculptor José Balcells featuring the silhouette of an albatross, in remembrance of the sailors who died while attempting to "round the Horn". It was erected in 1992 through the initiative of the Chilean Section of the Cape Horn Captains Brotherhood. Due to severe winds characteristic of the region, the sculpture was blown over in 2014. A 2019 research expedition found the world's southernmost tree growing, a Magellan's beech mostly bent to the ground, on a northeast-facing slope at the island's southeast corner. Cape Horn is the southern limit of the range of the Magellanic penguin.

Climate

The climate in the region is generally cool, owing to the southern latitude. There are no weather stations in the group of islands including Cape Horn, but a study in 1882–1883 found an annual rainfall of 1,357 millimetres (53.4 inches), with an average annual temperature of 5.2 °C (41.4 °F). Winds were reported to average 30 kilometres per hour (8.3 m/s; 18.6 mph), (5 Bf), with squalls of over 100 kilometres per hour (27.8 m/s; 62.1 mph), (10 Bf) occurring in all seasons. There are 278 days of rainfall, (70 days snow) and 2,000 millimetres (79 inches) of annual rainfall. Cloud coverage is generally extensive, with averages from 5.2 eighths in May and July to 6.4 eighths in December and January. Precipitation is high throughout the year: the weather station on the nearby Diego Ramírez Islands, 109 kilometres (68 miles) south-west in the Drake Passage, shows the greatest rainfall in March, averaging 137.4 millimetres (5.4 in); while October, which has the least rainfall, still averages 93.7 millimetres (3.7 in). Wind conditions are generally severe, particularly in winter. In summer, the wind at Cape Horn is gale force up to 5 percent of the time, with generally good visibility; however, in winter, gale-force winds occur up to 30 percent of the time, often with poor visibility.

Many stories are told of hazardous journeys "around the Horn", most describing fierce storms. Charles Darwin wrote: "One sight of such a coast is enough to make a landsman dream for a week about shipwrecks, peril and death."

The region experiences barely 7 hours of daylight during the June solstice, with Cape Horn itself having 6 hours and 57 minutes. The region experiences around 17+1⁄2 hours of daylight during the December solstice, and experiences only nautical twilight from civil dusk to civil dawn. White nights occur during the week around the December solstice.

Cape Horn yields a polar climate (ET), with abundant precipitation—much of which falls as sleet and snow.

Political

Cape Horn is part of the Commune of Cabo de Hornos, whose capital is Puerto Williams; this in turn is part of Antártica Chilena Province, whose capital is also Puerto Williams. The area is part of the Magallanes y la Antártica Chilena Region of Chile. Puerto Toro, a few miles south of Puerto Williams, is the closest town to the cape.
