When to See Northern Lights
The aurora season in Iceland runs from September through March when nights are dark enough. Peak activity is typically around the equinoxes in September and March.
The Science Behind the Northern Lights
The aurora borealis occurs when charged particles from the sun—carried by the solar wind—interact with Earth's magnetosphere. These particles are funneled toward the magnetic poles, where they collide with oxygen and nitrogen molecules in the upper atmosphere at altitudes of 80 to 300 km.
The colors depend on which gas is excited and at what altitude. Green, the most common color visible in Iceland, is produced by oxygen at around 100–300 km. Red hues appear at higher altitudes (above 300 km), while purple and blue tones come from nitrogen molecules. During strong geomagnetic storms, all colors may appear simultaneously across the sky.
Iceland's position at 64–66°N places it directly beneath the auroral oval—the ring-shaped zone of maximum aurora activity that encircles the geomagnetic pole. This means that even moderate solar activity can produce visible displays, making Iceland one of the most reliable aurora destinations in the world.
