Sturgeon Moon 2026: When It Peaks & What the Name Really Means

August’s full Moon is almost here—and this year, the Sturgeon Moon comes with an extra reason to look up: a dramatic partial lunar eclipse.

Mark your calendar for the night of Thursday, August 27, into Friday, August 28, 2026. The next full Moon, traditionally known as the Sturgeon Moon, reaches peak illumination at 12:18 a.m. EDT on Friday, August 28.

For most of North America, that means Thursday evening, August 27, is the night to watch.

And this August full Moon has a bonus: during the same night, Earth’s shadow will cover roughly 96% of the Moon, creating a deep partial lunar eclipse visible across much of the Americas.

When Is the Sturgeon Moon in 2026?

Here are the important times for the August full Moon:

• Eastern: 12:18 a.m. EDT, August 28
• Central: 11:18 p.m. CDT, August 27
• Mountain: 10:18 p.m. MDT, August 27
• Pacific: 9:18 p.m. PDT, August 27

The U.S. Naval Observatory lists the official full-Moon moment as 04:18 UTC on August 28.

You don’t have to catch that exact minute, though. To the naked eye, the Moon will appear essentially full throughout Thursday night and will still look impressively round the following evening.

Why Is It Called the Sturgeon Moon?

Like many traditional full-Moon names, Sturgeon Moon is tied to the seasonal rhythms of the natural world.

The name has long been associated with the lake sturgeon, the enormous freshwater fish once found in great abundance throughout the Great Lakes and other major waterways. Historical accounts associated with the Moon name note that sturgeon were easier to catch during this part of the year. NASA also lists Sturgeon Moon among the traditional names commonly used for August’s full Moon.

And these are no ordinary fish.

Lake sturgeon are living relics whose ancestors date back well over 100 million years. Some can grow more than 7 feet long, weigh hundreds of pounds, and live for a century or more. Sturgeon have also held deep cultural importance for Indigenous peoples throughout the Great Lakes region. Today, restoration efforts are underway to help populations recover after generations of overfishing, habitat loss, and dam construction.

Other Names for the August Full Moon

Sturgeon Moon isn’t the only traditional name connected to August’s full Moon.

Depending on the culture, region, and tradition, August Moon names have included:

• Green Corn Moon
• Grain Moon
• Red Moon
• Barley Moon
• Herb or Wyrt Moon

Notice a pattern? Many refer to ripening crops and the approaching harvest.

That’s fitting for late August, when summer is still very much with us—but the signs of the coming season are beginning to appear everywhere.

Don’t Miss the Lunar Eclipse

This is what makes the 2026 Sturgeon Moon especially noteworthy.

Just minutes before the Moon reaches full phase, it will be near the deepest point of a partial lunar eclipse.

NASA calculates that at greatest eclipse, around 12:13 a.m. EDT on August 28, approximately 96.3% of the Moon’s disk will be inside Earth’s dark umbral shadow.

That’s almost a total lunar eclipse.

The partial phase begins around 10:34 p.m. EDT on Thursday, August 27, as Earth’s shadow appears to take an increasingly large “bite” out of the Moon. Near maximum eclipse, only a thin portion will remain brightly illuminated, while much of the shadowed Moon may take on a dusky reddish or copper color.

Best Way To See the Sturgeon Moon

You won’t need a telescope—or even binoculars.

Start looking east after sunset on Thursday, August 27. A nearly full Moon rising close to the horizon can be especially striking, thanks to the familiar “Moon illusion” that makes it appear enormous beside trees, barns, mountains, and buildings.

For the best view:

• Find a location with a clear eastern and southeastern horizon.
• Get away from bright streetlights if possible.
• Watch the Moon earlier in the evening for a beautiful moonrise.
• Stay outside later to watch Earth’s shadow slowly cross the lunar surface.
• Binoculars can reveal impressive crater and surface details, but your eyes are all you really need.

And don’t worry if clouds interfere with the exact peak. The Moon will look nearly full on the nights immediately before and after August 28.

A Late-Summer Moon Worth Staying Up For

There is something unmistakably old-fashioned about stepping outside on a warm August night simply to watch the Moon rise.

For generations, full Moons helped mark the passing seasons—the ripening corn, the gathering grain, the movement of fish, and the slow turn toward autumn.

This year’s Sturgeon Moon offers an unusually spectacular reminder.

Look up Thursday night, August 27. The next full Moon is coming—and for a few hours, Earth itself will cast its shadow across it.
