Strawberry Moon 2021: How and when you can watch the last supermoon of the year

The first full ‘Strawberry’ moon of summer will also be the final supermoon for 2021, as it rises above the horizon Thursday, June 24. It will appear bigger and brighter than usual in the sky thanks to it being closer to Earth than normal.

June’s full ‘Strawberry’ moon will reach its peak in brightness at 7.39pm on June 24. The best views for people in the UK, will be at about 9.40pm. It will be visible to the naked eye for a few days and is the sixth full moon this year.

According to The Old Farmer’s Almanac, the Algonquin, Ojibwe, Dakota, and Lakota peoples, among others, call it the “strawberry moon” because it happens around the same time that berries are ready to be gathered.

Another European name for this full Moon is the Rose Moon. Some sources indicate the name “Rose Moon” comes from the roses that bloom this time of year. Others indicate that the name comes from the colour of the full Moon this time of year. Other seasonal names for this full Moon that I have found mentioned in various sources (sometimes with European and sometimes with Native American origins that I have not yet been able to check up on) are the Flower Moon, Hot Moon, Hoe Moon, and Planting Moon.

For Hindus, this full Moon corresponds with Vat Purnima. During the 3 days of this full Moon, married women will show their love for their husbands by tying a ceremonial thread around a banyan tree. The celebration is based on the legend of Savitri and Satyavan. 

For Buddhists, this full Moon is the Poson Poya. The Poson holiday in Sri Lanka celebrates the introduction of Buddhism in 236 BCE.

Another tribe has also given a name to this full Moon. This tribe is now scattered but mostly lived in the mid-Atlantic region of the United States. This tribe’s language is primarily English, but with a liberal smattering of acronyms, arcane scientific and engineering terms, and Hawaiian phrases (cheerfully contributed by the Deputy Project Manager). Comprised of people from all backgrounds, many of whom have gone on to join other tribes, this tribe was devoted to the study of the Moon. This tribe calls June’s full Moon the LRO Moon, in honour of the spacecraft they launched toward the Moon on June 18, 2009. 

Different publications use slightly different thresholds for deciding when a full Moon is close enough to the Earth to qualify as a supermoon. For 2021, some publications consider this full Moon the last of a series of four supermoons (from March to June). Other publications do not consider this a supermoon, as it is farther from Earth (and smaller in apparent size and brightness) than the previous three full Moons.
