Aurora tonight in Dunedin

Can you see the aurora australis from Dunedin?

The southern lights sit over the magnetic pole the same way the northern lights do, which means Dunedin looks south for them — and is subject to exactly the same Kp index that aurora watchers in the Arctic follow.

Dunedin needs Kp 6 and is the most accessible of New Zealand's southern aurora cities. It sits on a harbour with hills behind it, which is ideal geometry: the town's light is contained to one side, and the open coast faces the southern horizon where the aurora australis appears.

When to look: the Dunedin aurora season

The calendar is not the constraint at Dunedin — the sun clears 18° below the horizon on all 365 nights, so the sky is dark enough whatever month you pick. Pick the night with the clearest forecast instead, and expect the southern winter to give you the most hours in which to use it.

There is no bright season to work around at Dunedin. The sun clears 67.6° below the horizon at midwinter and stays dark enough on every night of the year, so the question is never whether the sky will be dark — only whether it will be clear.

Where to go in Dunedin

The Otago Peninsula and the beaches immediately south of the city give you dark, open coastline facing the right way.

Direction matters as much as darkness. The display will be over the magnetic pole, which from Dunedin means the southern sky — so pick a viewpoint with nothing between you and that horizon, and put any streetlight behind you. Tonight's "best window" figure above is the first hour where cloud falls below about 40% inside this latitude's dark period.

What Kp do you need in Dunedin?

The table below converts the abstract Kp index into what it actually means from Dunedin, using its magnetic latitude of -45.9° and threshold of Kp 6:

Two things have to line up for Dunedin: the planetary index has to reach about Kp 6, and the local sky has to be clear. Kp is a three-hour planetary average, so a display can start and fade inside one interval, and short substorm bursts routinely outperform the headline number. When the answer above says MAYBE, that usually means the geomagnetic side is fine and cloud is the question.

How tonight's answer is calculated for Dunedin

Five inputs produce the answer at the top of this page, and every one of them is specific to Dunedin: the NOAA Kp forecast against a threshold of Kp 6 (35% of the score), cloud cover through the night at -45.87°, 170.50° (25%), the moon (15%), astronomical darkness at this latitude (15%), and light pollution at Bortle 5 (10%). How the score is built, where the numbers come from and where the method can go wrong are all set out on our methodology page. There is nothing to install and nothing to sign up for: the calculation runs in your browser against NOAA and Open-Meteo.
