A live, honest answer to “will I see the aurora australis in New Zealand tonight?” — computed from NOAA's real-time feeds against New Zealand's actual magnetic latitude, with the uncertainty stated. The full 3D live sky renders these same feeds through the observatory's photo-validated model.
Aurora needs darkness: get away from town lights, adapt your eyes for fifteen minutes, and face the open ocean to the south.

The South Island's southern coast is the best aurora australis latitude with a road to it: Dunedin and Southland see displays at G1–G2, and Stewart Island — Rakiura, 'glowing skies' in Māori — was named for them.
Magnetic latitude — not geographic — decides who sees a given storm, and New Zealand's key viewing latitude sits near -50° magnetic. As a rule of thumb from NOAA's Kp view-line:
| Activity | What you'd see in New Zealand |
|---|---|
| Kp 8 (G4 storm) | Aurora low on the southern horizon from a dark site |
| Kp 9 (G5 superstorm) | Displays climbing high — structure, motion, color overhead possible |
Rule-of-thumb only — substorm timing, Bz, and your local darkness matter as much as Kp. The live view runs the full model for this exact spot, and the field guide explains the numbers. A camera on a tripod catches aurora one storm class earlier than your eyes will.
The Otago Peninsula near Dunedin is the anchor: it pairs the region's best darkness with an open view toward the aurora. Also worth knowing: the Catlins, Southland, and Stewart Island / Rakiura — a certified dark-sky sanctuary.
Wherever you stand, the rules are the same — get away from town glow, put a low, open horizon to the southern, and give your eyes fifteen minutes to adapt. No screen time while you wait.
The season is March to September — the southern winter — with the weeks around the equinoxes statistically strongest. Summer nights are short and bright this far south. Statistically, the strongest hours are around local magnetic midnight — roughly 10 pm to 2 am. Substorms come in cycles an hour or more apart, so a promising night deserves more than one look. A bright moon washes out faint displays; check the phase before driving.
Moon discipline is stricter here than under the northern oval: most Otago displays are marginal, horizon-hugging glows over the sea, and a bright moon kills them outright. Aim for the week either side of new moon, and treat a fresh southerly clearance as the signal to drive.
The peninsula's outer side turns its back on Dunedin's lights. The inlet's tidal flats mirror a glow at water level, while Sandfly Bay's dune crest gives an elevated line over open Southern Ocean.
A lighthouse headland with nothing between you and Antarctica but water. The walk from the car park is short, and the entire southern sweep is ocean horizon.
A certified dark-sky sanctuary where the name itself means glowing skies. Short walks from Oban reach south-facing shores; the trade-off is ferry-dependent access and famously changeable weather.
Slope Point is the South Island's true southern tip, reached across farmland. Bluff Hill offers the drive-up alternative — a sealed road to a panorama south over Foveaux Strait, high enough to sit above the port lights below.
Face south — this is the aurora australis, and everything happens over the ocean. The headline thresholds are steep: roughly Kp 8 for a bright display standing off the horizon and Kp 9 for overhead structure. But Dunedin's regulars work far below that, because at G1–G2 a camera pointed over the sea pulls beams and color out of what the eye reads as pale haze. At moderate Kp, expose first: a fifteen-second frame toward Foveaux Strait or the open Pacific decides the night.
