Spring Thaw in southern Finland
Southern Finland's landscape is defined by an intricate network of forests, lakes, and low-lying coastal areas shaped by ancient glaciers. This ecosystem plays a key ecological role, supporting freshwater habitats, regulating regional water cycles, and storing significant amounts of carbon within its vast woodlands and wetlands.
In early spring, the region undergoes a marked seasonal transition as temperatures rise and sea ice breaks up. This image, acquired by one of the Copernicus Sentinel-2 satellites on 24 March 2026, shows this shift across southern Finland, including Turku, Salo, and Helsinki. Dark blue open waters dominate the western Gulf of Finland, while fragmented ice floes are visible in pale tones along the coastal areas. Inland, frozen lakes appear as fragmented light blue surfaces, and the landscape shows snow-free terrain in browns and greens, with forests and agricultural areas now visible.
Sentinel-2 data provides consistent observations of ice conditions, supporting navigation safety, environmental monitoring, and seasonal assessments across the Baltic Sea region.
