The Full Sturgeon Moon of August 2026 will peak on Friday, August 28, marking the traditional Full Moon of late summer. Why do we call it the Sturgeon Moon? Is it full of fish? We’ll explain what makes the August Moon special and how to view this gorgeous summer sight best.

When to See the Full Moon in August 2026

August’s Full Moon will crest on Friday, August 28, reaching peak illumination at 12:18 A.M. Eastern Time. Look up on the evening of Thursday, August 27, to catch a spectacular view of the Full summer Moon. You can convert 12:18 A.M. Eastern Time to your time zone using our tool.

Why Is It Called the Sturgeon Moon?

The Full Moon of August is traditionally called the “Sturgeon Moon.”

The Full Moon names used by The Old Farmer’s Almanac have different origins, including Native American, Colonial American, and European sources. Traditionally, each Full Moon name was applied to the entire lunar month in which it occurred, not solely to the Full Moon.

The Sturgeon Moon

The name Sturgeon Moon comes from the giant lake sturgeon of the Great Lakes and Lake Champlain; this native freshwater fish was readily caught during this part of summer and an important food staple for Native Americans who lived in the region. At one time, the lake sturgeon were quite abundant in late summer, though they are rarer today.

What Is a Sturgeon?

These prehistoric-looking fish have been traced back to around 136 million years ago, and many people call them “living fossils.”

  • Females require around 20 years to start reproducing, and they can reproduce only every 4 years. However, they can live up to 150 years!
  • Today, there are about 29 species worldwide, including the lake sturgeon found in the Great Lakes. They have evolved in size from the size of a bass to a monster sturgeon as big as a Volkswagen.
  • The lake sturgeon is quite rare today due to intense overfishing in the 19th century, pollution, and damage to their habitat.

The word “sturgeon” means “the stirrer,” which is what this giant fish does when it is looking for food; it stirs up the mud and silt on river and lake bottoms. Notice the pointed snout and whisker-like tactile organs near the mouth. Credit: Tennessee Aquarium.

Alternative August Moon Names

Flying Up Moon is a Cree term describing the time when young birds are finally ready to take the leap and learn to fly. 

Corn Moon (Algonquin, Ojibwe), Harvest Moon (Dakota), and Ricing Moon (Anishinaabe) signify that this is the time to gather maturing crops. Along the same vein, the Assiniboine people named this period Black Cherries Moon, referring to when chokecherries become ripe.

The Tlingit people of the Pacific Northwest traditionally called this time of the season the Mountain Shadows Moon.

Next year, 2023, we'll have two full moons in August. So, which will be called the Sturgeon Moon? 1st (UTC), or 31st (UTC), or both? If not both, what will be a name for the other one? My idea is, 1st: Sturgeon / 31st: Blue, and this wil be applied to another month too (I mean, May 31st of 2026's moon also will be a Blue moon, not a Flower moon). Is this correct? As this is not the first case definitely, there must be an answer already. But I cannot find it. Thank you for your help.

You are correct. The first full Moon typically goes by the most popular name (Sturgeon Moon, in the case of August). The second full Moon in any calendar month is known as a Blue Moon, but it may also go by one of the month's other Moon names (such as Flying Up Moon or Black Cherries Moon for August).

Thank you! I understand very well. I hope you see beautiful moons :D

Even though the full moon is slightly visible tonight (08-21-21) & then illuminates fully tomorrow morning , it is still ONE full moon. Therefore, I don’t agree with the idea that this current full moon is also a blue moon. The name Blue moon is given to the second full moon in a calendar month. This moon is unique, absolutely, but it doesn’t fit the title of a blue moon.

I agree 100% ....right...
