Strawberry Moon to Illuminate Finnish Skies Tonight
The first full moon of June, known as the strawberry moon, will reach its peak in Finland in the early hours of Tuesday. Yle reports that the most striking view will occur at 02:56, when the moon will be at its fullest.
The strawberry moon derives its name from the ripening of berry harvests, particularly strawberries, during this time of year. According to Yle, the term originates from Indigenous peoples in North America, including the Lakota, Ojibwe, and Algonquin, for whom the full moon signaled the start of the strawberry-picking season. Despite its name, the moon’s color is not inherently different, though atmospheric conditions can give it a reddish hue.
Ilta-Sanomat explains that the moon’s reddish appearance is caused by moonlight passing through Earth’s atmosphere, which scatters blue light and allows more red light to reach observers. Humidity and impurities in the air can further enhance this effect. Tieteen Kuvalehti (via Ilta-Sanomat) notes that the moon’s low trajectory across the sky—just over 1.5 degrees above the horizon at its highest—will make it difficult to observe in most of Finland. The Astronomical Association Ursa states that the strawberry moon will not rise above the horizon at all in Jyväskylä or farther north, and visibility will be limited even in southern regions, with the best views likely near the seashore.
The Independent (cited by Ilta-Sanomat) reports that this year’s strawberry moon will be the lowest full moon visible until 2043, which may also make it appear larger than usual due to its proximity to the horizon. Yle advises those hoping to catch a glimpse to look toward the southeast-south direction between Monday and Tuesday night, weather permitting. The moon’s low path is a result of its occurrence shortly after the summer solstice.
