Why this forecast?
Aurora Zone
Higher Aurora Zone = better aurora visibility. Your location's Aurora Zone determines how often auroras appear overhead.
Status Levels:
Kp index
Kp measures global magnetic disturbance. Higher Kp = stronger auroras visible at lower latitudes.
Status Levels:
Cloud Cover Impact
Clear skies are essential for aurora viewing. Clouds block your view of the northern lights. The percentage shows cloud coverage (0-25% = clear, 85%+ = overcast).
Status Levels:
Moonlight
Bright moonlight can wash out faint auroras. New moon provides the darkest skies for optimal viewing.
Status Levels:
Darkness
Darker skies are essential for aurora viewing. The sun must be below the horizon for auroras to be visible.

Aurora is Rare in Basel — But Not Impossible
Aurora Borealis Viewing in Basel
Northern border city with best aurora potential in Switzerland.
Basel sits at 44.6° magnetic latitude, which means aurora typically becomes visible when the Kp index reaches 9+. Aurora sightings in Basel require stronger geomagnetic storms (Kp 9+), which occur a few times per year. When storms do hit, the best viewing window is 10 PM to 2 AM local time under clear, dark skies.
