Kurjenrahka - Northern Lights - Southern Finland

This forecast tracks when Southern Finland's rare aurora opportunities align with clear skies and darkness. At 60°N, Helsinki sits at the same latitude as Shetland—aurora displays are visible during strong geomagnetic storms, typically requiring Kp 5 or higher.

What makes Southern Finland special for aurora photography:

• Helsinki harbor foregrounds - Combine aurora with Suomenlinna fortress, icebreakers, and maritime architecture
• Lake reflections - The region's 188,000 lakes create mirror shots impossible in landlocked areas
• Dark sky accessibility - Nuuksio National Park sits just 30km from Helsinki with minimal light pollution
• Baltic coastline - Porvoo and coastal viewpoints offer unobstructed northern horizons

Peak aurora season runs from September through March. Unlike Finnish Lapland where aurora is frequent, Southern Finland sees displays only during major geomagnetic storms—but when conditions align, the combination of urban foregrounds and lake reflections creates unique compositions unavailable further north. Seek locations outside Helsinki's light dome, particularly Nuuksio's lakes or coastal vantage points east of the city. The forecast helps identify those rare clear nights when strong geomagnetic activity reaches this latitude.
