Southern Lights Forecast
for Christchurch
Christchurch, New Zealand — about -47° geomagnetic latitude. Lower frequency than far-south sites.
Can you see the aurora in Christchurch?
Yes. From a dark site you need about Kp 6 for a faint glow low on the southern horizon, and roughly Kp 8 for bright aurora directly overhead. At -47° geomagnetic latitude this spot sits well outside the oval — it takes a major geomagnetic storm.
Over the last 12 months the planetary Kp peaked at the levels Christchurch needs on the days shown — out of 365. Kp is a global index, so these are the odds the sky was active enough; you still need clear, dark skies here. In 94 years on record the strongest day hit Kp 9.

The season runs late March to late September, when the nights are long and dark. You also need clear skies and a low moon — even a strong Kp is useless under cloud. Check tonight's live call above, then plan a night around the dark window, cloud and moon.
