Moon Phase Finland
Moon Phase Finland: Last Quarter
On Sunday 4 October 2026, the moon phase today in Finland is a Last Quarter, with 46% illumination. Next full moon: 26 Oct.
The Moon wobbles slightly as it orbits Earth — a phenomenon called libration. Hit Animate Day to watch the surface shift live. Over time, this lets us see 59% of the lunar surface rather than just 50%.

Understanding the Moon's Phases
The Moon itself never changes shape — what changes is the angle at which sunlight falls across its surface. Over the course of a 29.5-day orbit around Earth, that shifting angle cycles through eight recognizable phases, each offering something different to watch for.
Watching the Moon from Finland
Finland stretches from about 59.8°N on the south coast to 70.1°N at the northern tip, with about a third of the country north of the Arctic Circle, so the Moon's path changes dramatically with the seasons and with how far north you are. A full Moon near the winter solstice climbs to around 53° above the southern horizon in Helsinki and about 43° at the northern tip, while a full Moon near the summer solstice peaks at only about 6° in Helsinki and never clears the horizon in the far north. Above the Arctic Circle the Moon can stay above the horizon for a day or more around a midwinter full Moon, and fail to rise for a day or more in midsummer. The light changes just as much: around midsummer the Sun stays within about 6° of the horizon all night in Helsinki, so for weeks the sky never gets dark, and in the far north the Sun does not set at all, while midwinter brings the polar night. That makes autumn to spring the season for faint galaxies and nebulae on a new Moon night, and for the aurora, which a bright Moon can wash out when it is faint, though strong displays stay visible.
