Leonids in Buenos Aires

The Leonids meteor shower peaks from Buenos Aires around Nov 17, with up to 15 meteors per hour under ideal conditions. In 2026 a thin crescent moon leaves mostly dark skies, and from Buenos Aires the radiant in Leo climbs to 17° above the north-east horizon around 04:00. Local best viewing window: 03:10–04:00 UTC-03 on the peak night, about 0.8 hours of astronomical darkness. Scaled to that altitude, the 15/hour headline figure works out to roughly 4 meteors an hour from Buenos Aires under a genuinely dark sky. The radiant stays low from Buenos Aires, so expect fewer meteors but longer, shallower trails near the horizon. Tonight: complete cloud cover across the forecast window.
