Aurora australis in Dunedin tonight
Otago, New Zealand · 53° magnetic latitude · Kp 4-5 threshold
Kp 1 is well below the Kp 4-5 threshold needed for aurora to be visible from Dunedin.
7-day outlook for Dunedin
Tonight shows the live Kp reading. The nights after it show the Kp expected from any coronal mass ejection DONKI predicts will arrive that day, and a quiet baseline of Kp 2 where no arrival is forecast.
Based on CME arrival predictions from NASA DONKI. Arrival times ±6 hours.

What Kp is needed here?
Dunedin sits at a magnetic latitude of approximately 53°S. The Kp index - a global measure of geomagnetic activity on a scale from 0 (quiet) to 9 (extreme storm), updated every 3 hours - needs to reach Kp 4-5 before the auroral oval expands far enough north to be visible from here.
At Kp 4-5, visibility is possible from Dunedin but skies need to be clear and dark. Cloud cover and light pollution remain the main obstacles even when Kp is high enough.
Best dark sky sites near Dunedin
Light pollution is the biggest obstacle after cloud cover. These sites give you the best dark southern horizon within reach.
Sandfly Bay (Otago Peninsula)
Get directions ↗A south-facing bay on the outer Otago Peninsula, 35 km from Dunedin central. The beach faces south-southeast across open Pacific with no land between it and Antarctica in that direction. Properly dark - the walk in from the car park takes 20 minutes across sand dunes. One of the most accessible extreme dark sky positions in the South Island. The Royal Albatross Centre at Taiaroa Head is 5 km away and similarly dark.
Taiaroa Head (Otago Peninsula tip)
Get directions ↗The tip of the Otago Peninsula at the entrance to Otago Harbour. Faces south and southeast across open ocean. The Royal Albatross Centre car park is accessible year-round. The lighthouse and headland give an elevated position above the harbour entrance. Light pollution from Dunedin city is behind you when facing south from the head. 45 km from Dunedin central.
Tomahawk Beach / St Clair area
Get directions ↗The Dunedin ocean beach suburb of St Clair faces southeast. The beach itself gives an open ocean horizon. Light pollution from Dunedin is visible to the north and west but the southern horizon is dark. Within 5 km of the city centre - the most accessible option for Dunedin residents during a brief aurora window. At Kp 5+, this position is usable for low aurora on the southern horizon.
Best time to see the aurora australis in Dunedin
At 53°S magnetic latitude, Dunedin sits at the outer edge of regular aurora australis territory. Only the southern winter months, May through July, occasionally bring storms powerful enough to push the oval this far north. Outside this window, there is insufficient darkness for aurora to be visible.
Activity peaks around the March and September equinoxes, when Earth's magnetic field geometry is most favourable for coupling with the solar wind. These windows produce the strongest aurora australis events of the year for observers at this latitude.
Outside May through July, twilight prevents aurora visibility even during significant geomagnetic storms. The season is short, but equinox months on either side of winter can extend it when timing is favourable.

How often does the aurora appear in Dunedin?
Average nights per month the Kp reached Dunedin's threshold of 5+, from 15 years of geomagnetic data (2010–2024).
Counts the Kp 5+ threshold only - cloud cover and local darkness are not included.

Plan your trip to Dunedin
Best window
The August to October window averages 9 aurora nights - the strongest consecutive stretch of the year.
How long to stay
For your best chance in September, plan at least 13 nights.
Aurora activity peaks at the March and September equinoxes in both hemispheres. This is driven by the angle of Earth's magnetic field relative to the solar wind, not by local seasons. Winter months at this latitude offer longer dark nights for observing, but March and September average the highest number of aurora nights in the historical data.
