Leonids in São Paulo

The Leonids meteor shower peaks from São Paulo 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 São Paulo the radiant in Leo climbs to 29° above the north-east horizon around 03:45. Local best viewing window: 02:25–03:45 UTC-03 on the peak night, about 1.3 hours of astronomical darkness. Scaled to that altitude, the 15/hour headline figure works out to roughly 7 meteors an hour from São Paulo under a genuinely dark sky. The radiant stays low from São Paulo, so expect fewer meteors but longer, shallower trails near the horizon. Tonight: fully overcast — little chance of a clear gap.
