Named After a Big Old Fish

The Full Moon in August is called Sturgeon Moon because of the large number of sturgeon fish that were found in the Great Lakes in North America this time of year.

The most common sturgeon in the Great Lakes is the lake sturgeon—males have a life span of 55 years, while females can live up to 150 years! It is also the American continent’s largest freshwater fish and can grow to over two meters long (6 feet) and weigh around 90 kilos (200 pounds).

Lake sturgeon was essential for Native American tribes living in the area and is the oldest and largest native species in the Great Lakes—the largest surface freshwater system in the world.

Start of Harvesting Season

Inspired by the harvest and abundance of crops at the start of the harvesting season in the Northern Hemisphere, an English name for the August Full Moon is Corn Moon. The Anglo-Saxons also called it the Grain Moon.

The Celts called it Lynx Moon and Dispute Moon, pointing to the delicate balance of nature and harvest. Another English name is Lightning Moon, after Northern Europe’s more frequent thunder and lightning storms in late summer.

12 Full Moon Names

The Full Moon has been integral to tracking the change of months and seasons since ancient times.

Today, we use many of these ancient month names as Full Moon names, and many of them come from the Colonial Americans adopting Native American names into their calendars.

Although the most commonly used Full Moon names are English interpretations of Native American names, some are also Celtic, Anglo-Saxon, medieval English, and Neo-Pagan.
