Southern Delta Aquariids in London

The Southern Delta Aquariids meteor shower peaks from London around Jul 29-30, with up to 25 meteors per hour under ideal conditions. In 2026 a bright moon will hide most meteors except the brightest, and from London the radiant in Aquarius climbs to 21° above the south horizon around 02:20. Local best viewing window: 00:40–02:20 BST on the peak night, about 1.7 hours of astronomical darkness. Scaled to that altitude, the 25/hour headline figure works out to roughly 9 meteors an hour from London under a genuinely dark sky. The radiant stays low from London, so expect fewer meteors but longer, shallower trails near the horizon. Tonight: complete cloud cover across the forecast window.
