Is Invercargill the best mainland NZ spot for aurora?
It is the southernmost city, so displays that stay on the horizon elsewhere climb higher here. Combined with Oreti Beach and Bluff's sea horizons, it is a strong claim, with Dunedin its main rival.
What about Stewart Island / Rakiura?
Across Foveaux Strait, Rakiura is an International Dark Sky Sanctuary with essentially zero light pollution, the premium option if the ferry or flight schedule cooperates.
Can I see the southern lights in Invercargill tonight?
Aurora is possible near Invercargill, but it may require a camera, a darker location, or a stronger-than-forecast Kp pulse.
What matters most for Invercargill?
