August's full moon

The Sturgeon Moon

August's full moon — named for the giant sturgeon once caught in abundance in the Great Lakes. The lore, the look, and how to see it.

Short answer
The Sturgeon Moon is August's full moon, named by Great Lakes tribes for the giant lake sturgeon most easily caught at this time of year. A late-summer moon, it still rides fairly low and often glows warm and golden near the horizon.

When is the Sturgeon Moon?

In 2026 the Sturgeon Moon peaks on August 28 at 04:18 UTC (12:18 AM EDT / Aug 27, 9:18 PM PDT) — during a partial lunar eclipse. In 2027 it falls on August 17.See 2026 calendar

Why "Sturgeon"?

The name comes from the tribes around the Great Lakes and Lake Champlain, where the prehistoric-looking lake sturgeon were most readily caught in late summer. The same August moon was also called the Green Corn Moon, the Grain Moon, and the Red Moon for the reddish tint it often takes through summer haze.

What it looks like

As a late-summer full moon, the Sturgeon Moon still follows a relatively low path and spends a long time near the horizon, where summer haze and extra atmosphere often lend it a warm amber or reddish tint at moonrise.

2026: a bite taken out of the Sturgeon Moon

The 2026 Sturgeon Moon rises into a partial lunar eclipse on August 28: Earth's shadow clips the full Moon, darkening a visible bite of its disk at maximum. Unlike March's total eclipse, this one favors the Atlantic side — the Americas, Europe and Africa — and needs no equipment or eye protection, just a glance up at the right hour. It is the second lunar eclipse of 2026, making this one of those years when both eclipse seasons deliver on the same-named calendar.

An extra gift of the timing: because the full moon falls at the very end of August, the Perseid meteor shower two weeks earlier (August 12–13) peaks under a dark, moonless sky — the best possible configuration, and worth an extra night out.

A fish older than the dinosaurs' end

The lake sturgeon that named this moon deserves its own paragraph: an armor-plated giant that can pass two metres in length, live far beyond a human lifetime — females routinely reach 80–150 years — and whose lineage has swum essentially unchanged for over 100 million years. For the peoples of the Great Lakes it was a staple whose late-summer abundance marked the season as reliably as any star. Overfishing nearly erased it in the 20th century; the moon name is now, in part, a memorial to how plentiful it once was.


Frequently asked questions

Why is it called the Sturgeon Moon?
Because August was when the large lake sturgeon of the Great Lakes were most easily caught, according to the Native American tribes of that region.
Why does the Sturgeon Moon look reddish?
Late-summer haze and its low path mean its light passes through extra, often hazy atmosphere near the horizon, which can give it a warm red or amber tint.
When exactly is the Sturgeon Moon in 2026?
It reaches fullness on Friday, August 28, 2026 at 04:18 UTC — 12:18 AM EDT, or 9:18 PM PDT on the evening of August 27 — coinciding with a partial lunar eclipse visible from the Americas, Europe and Africa.
Does the 2026 Sturgeon Moon affect the Perseids?
Favorably: with the full moon on August 28, the Perseid peak on August 12–13, 2026 happens near new moon under dark skies — the best viewing circumstances the shower can get.
