The Strawberry Moon is a well-recognized full moon event that graces the night sky each year. It represents a recurring moment in the lunar cycle, prompting curiosity about its visual characteristics and cultural significance.
Its True Appearance
While the name “Strawberry Moon” might suggest a distinct pink or red hue, its actual appearance is similar to any other full moon. However, when low on the horizon, it can appear larger and take on an orange or reddish tint. This visual effect, known as the “moon illusion,” is a trick of perception rather than a physical change in the moon’s size.
The occasional reddish or amber color is due to a scientific phenomenon called Rayleigh scattering. When moonlight travels through a greater thickness of Earth’s atmosphere, particularly when the moon is low in the sky, shorter wavelengths of light, such as blue and violet, are scattered away by atmospheric particles. This allows longer wavelengths, like red and orange light, to pass through more directly to our eyes. The same principle explains why sunrises and sunsets often appear reddish.
For observers in the Northern Hemisphere, the June full moon, including the Strawberry Moon, often tracks a lower path across the sky than full moons at other times of the year. This low trajectory means its light consistently passes through more of the atmosphere, which can enhance the reddish or golden appearance.
The Origin of the Name
The name “Strawberry Moon” has deep roots in the traditions of various North American Indigenous tribes. This particular name was used to mark the season when wild strawberries reached their peak ripeness and were ready for harvesting. For these communities, the full moon in June served as a natural calendar, signaling the optimal time to gather the sweet fruit.
Tribes such as the Algonquin, Ojibwe, Dakota, and Lakota are among those credited with using this name. While “Strawberry Moon” is widely recognized, other Indigenous and European cultures had their own names for the June full moon, reflecting their local natural events or agricultural practices. Examples include the “Rose Moon” in Europe, referring to the blooming of roses, or the “Green Corn Moon” used by some Cherokee communities, denoting the sprouting of corn.
Observing the Strawberry Moon
For those interested in observing the Strawberry Moon, the full moon typically occurs in June, with the exact date varying each year. In 2025, for instance, the Strawberry Moon will reach its peak illumination on June 11. The moon appears full to the casual observer for approximately three days around this peak.
The most opportune time to view the Strawberry Moon is shortly after moonrise or just before moonset. During these periods, the moon is low on the horizon, which enhances the atmospheric effects that can give it a warm, reddish tint and make it appear larger. To maximize the viewing experience, finding a clear vantage point with an unobstructed view of the horizon is helpful. Checking local moonrise and moonset times for the specific date will allow for precise planning.
