Peak July 29–30, 2026 · full Moon (~99% lit), strong interference · up to ~25/hr · medium-paced (41 km/s) · radiant in Aquarius.
The Southern Delta Aquariids are a broad, gentle shower, best from the southern hemisphere and the tropics — no sharp spike, just a steady trickle of medium-paced meteors across late July and early August. Their tail overlaps the building Perseids, so late-July nights can show both. 2026 is a poor year for them, though, with a bright Moon washing out all but the brightest.
When it peaks in 2026 — and the Moon
The Southern Delta Aquariids peak in 2026 falls on the night of July 29–30, 2026. That night the Moon is a full Moon, around 99% lit — a bright near-full Moon that stays up for much of the night — so moonlight interference is strong. As every year, the Southern Delta Aquariids are best in the dark hours after midnight, when the radiant climbs high and the meteor rate builds toward dawn.
Where to look
The radiant sits in Aquarius, low in the south for northern observers and high overhead from the southern hemisphere — which is why the far south and the tropics get the best of this one. It climbs after midnight; face south and take in a wide stretch of sky.
What to expect
About 25 meteors an hour under ideal dark southern skies at the plateau; fewer from mid-northern latitudes where the radiant stays low — and fewer still in 2026 with the Moon so bright. The meteors are medium-speed (41 km/s) and often faint, so moonlight hits this shower harder than most.
What to bring
The Southern Delta Aquariids are a naked-eye event — comfort matters more than optics.
- A reclining or zero-gravity chair — you'll be looking up for a while
- A red-light headlamp — preserves your night vision
- Warm layers, a hat and a blanket — you cool off fast lying still
- A hot drink and patience — give your eyes 20+ minutes to adapt
Frequently asked
When do the Delta Aquariids peak in 2026?
They have a broad plateau rather than a sharp peak, centred on the night of July 29–30, 2026. Good rates run for a week or more either side, which is part of their appeal.
Will the Moon interfere in 2026?
Yes, badly — the Moon is nearly full around the peak and up for most of the night, so only the brightest Delta Aquariids will show. A dark, moonless year suits this faint shower far better.
Where are they best seen?
The southern hemisphere and the tropics, where the radiant climbs high. From mid-northern latitudes the radiant stays low in the south, so northern observers see a reduced display.
Where do they come from?
The likely parent is comet 96P/Machholz. The 'Southern' in the name distinguishes them from a weaker northern branch active around the same time.
