What is the Kp Index?

The Kp index measures global geomagnetic activity on a scale from 0 to 9. For Iceland (latitude 64–66°N), aurora becomes visible from around Kp 3 in North Iceland, and from Kp 4–5 across the whole country. A Kp of 7+ indicates a geomagnetic storm with spectacular aurora even in southern Iceland.

Kp 0–1 No aurora
Kp 2 Unlikely
Kp 3 Possible
Kp 4 Good chances
Kp 5–6 Excellent
Kp 7+ Geomagnetic storm

Best Aurora Viewing Spots in Iceland

Þórsmörk

Remote highland valley, zero light pollution, stunning mountain backdrop.

Snæfellsnes Peninsula

Away from Reykjavík — ideal dark sky conditions along the north shore.

Akureyri area

North Iceland base — aurora visible at lower Kp levels.

Kirkjufell, Grundarfjörður

Iconic mountain, one of Iceland's most photographed aurora spots.

Jökulsárlón Glacier Lagoon

Aurora reflecting in icebergs — spectacular if skies are clear.

Reykjanes Peninsula

Close to Reykjavík but darker. Good for a quick chase.

Aurora Hunting Tips

  • Check the forecast 1–2 hours before heading out — Kp can change rapidly.
  • Clear, dark skies are essential. Check cloud cover forecasts (vedur.is).
  • Face north and give your eyes 15–20 minutes to adjust to darkness.
  • Aurora apps and cameras can pick up activity your eyes may miss.
  • Best months: September through March (long nights in Iceland).
  • New moon periods give the darkest skies — plan around the lunar calendar.
