Night Sky Tonight in Torres del Paine

The live score above pulls today's forecast and runs it through StarCast's scoring model, factoring in cloud cover, moon illumination, Bortle class, humidity, and atmospheric transparency. Above 70 is an excellent night. Below 40, conditions are poor. The score updates daily.

Torres del Paine National Park in Chilean Patagonia is one of the most dramatic landscapes on Earth, where granite towers and spires rise thousands of feet above turquoise glacial lakes at the southern end of the Andes. At nearly 51 degrees south latitude, the park sits under some of the darkest and most pristine skies in the Southern Hemisphere, with Bortle Class 1 to 2 readings common across the surrounding wilderness. The Large and Small Magellanic Clouds — satellite galaxies of the Milky Way invisible from the Northern Hemisphere — are high overhead on clear nights, alongside a dense and brilliant southern star field. The Torres towers, Cuernos peaks, and glacially fed lakes provide foreground of unmatched drama for astrophotography. The park is one of the most photogenic night sky destinations on Earth.

At this southern latitude, the Milky Way's galactic core is visible year-round, though the austral summer months of November through February bring very long days that dramatically shorten the nighttime window. The austral winter from May through August offers the longest nights and the galactic core nearly overhead, but extremely cold temperatures and park infrastructure closures limit access. The shoulder seasons of March through April and September through October balance dark hours, galactic visibility, and reasonable conditions. Patagonian weather is notoriously unpredictable and wind is nearly constant — clear nights are genuinely precious and worth being ready for on short notice.
