The last full moon of summer 2026 arrives on Friday, 28 August — and this year’s event is especially notable. Not only does it mark the traditional August full moon, but it also coincides with a partial lunar eclipse. Adding to the occasion, Greece’s Ministry of Culture will open 126 archaeological sites, monuments, and museums across the country free of charge on the same day.
When and Where to Observe the Full Moon
The peak of the full moon occurs at 07:18 AM local time in Greece on 28 August. While that moment falls in the early morning, the Moon will already appear nearly full the previous evening. On Thursday, 27 August, the Moon rises in Athens around 7:43 PM, with approximately 98% of its visible face illuminated. By Friday evening, it rises slightly later — around 8:08 PM — but remains impressively bright and round.
For most skywatchers, the night of Thursday, 27 August offers the best viewing opportunity: the Moon will be high in the sky for much of the night, fully illuminated to the naked eye, and easily visible without special equipment. Exact moonrise and moonset times vary by location, so those planning photography or precise observation should consult local astronomical resources.
Why It’s Called the ‘Sturgeon Moon’
This August full moon is widely known in North American tradition as the Sturgeon Moon — named after the sturgeon, a large freshwater fish historically abundant in the Great Lakes region during this time of year. Indigenous communities relied on sturgeon runs in late summer, and the name reflects seasonal ecological patterns rather than astronomical properties. It is not an official astronomical term nor part of Greek folklore; Greek media use it mainly as a descriptive cultural reference.
Is It a Supermoon?
No. Despite occasional headlines, the August 2026 full moon is not a supermoon. A supermoon occurs when a full moon coincides closely with the Moon’s perigee — its closest point to Earth in orbit. According to available astronomical data for 2026, the year’s supermoon full moon falls in December, not August. Any impression of unusual size near the horizon is due to the well-documented Moon illusion: when the Moon is low, our brain compares it to terrestrial objects like trees or buildings, making it appear larger than when it’s high overhead.
A Rare Celestial Bonus: Partial Lunar Eclipse
In addition to the full moon, observers across Europe — including Greece — will witness a partial lunar eclipse on the same day. Though not total, the eclipse adds subtle visual interest as Earth’s shadow gradually covers part of the lunar surface. The exact timing and visibility depend on local conditions, but the event enhances the significance of this year’s August full moon as a dual celestial spectacle.
