A steady late-July stream of faint meteors, best from southern latitudes and a warm-up act for the Perseids.
Maximum: July 31, 2027 Active: Jul 12 – Aug 23
Viewing from New York
The Southern Delta Aquariids reach maximum on July 31, 2027, with a peak rate of up to 25 meteors per hour under ideal dark skies (active Jul 12 – Aug 23). The Moon is out of the way for most of the peak night, leaving dark skies. A favourable year. Rates stay elevated for several nights either side of the maximum, so you do not need to catch the exact peak night.
