Aurora australis Invercargill tonight
Invercargill is New Zealand's southernmost city at 58°S magnetic latitude - Kp 2–3 is the threshold from south-facing dark sites. This is a lower requirement than Queenstown (Kp 4–5), Dunedin (Kp 4–5), or Christchurch (Kp 5). Oreti Beach (10 km west) faces southwest over Foveaux Strait. Bluff (27 km south) gives the most southerly road-accessible mainland position. Face south. Peak season: May to August.

What Kp is needed here?
Invercargill sits at a magnetic latitude of approximately 58°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 2–3 before the auroral oval expands far enough north to be visible from here.
At Kp 2–3, visibility is possible from Invercargill 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 Invercargill
Light pollution is the biggest obstacle after cloud cover. These sites give you the best dark southern horizon within reach.
Oreti Beach
Get directions ↗A 30 km stretch of beach on the Invercargill Estuary facing west-southwest toward Foveaux Strait and the Southern Ocean. At night the beach is dark and exposed, with the Invercargill light dome to the east and open ocean to the west and south. Bortle Class 2-3 conditions on the beach itself. At 58°S magnetic latitude, Kp 2-3 is sufficient for aurora australis to appear above the southern and southwestern horizon. The beach faces directly toward the auroral oval during moderate geomagnetic activity. The long sand makes vehicle access possible to reach positions away from the township end, though soft sand off the access track is a risk. The beach is open all hours and well-known to local aurora photographers.
Bluff / Stirling Point
Get directions ↗Bluff is New Zealand's southernmost permanent town and the ferry terminal for Stewart Island. Stirling Point at the south end gives the most southerly road-accessible position on the South Island mainland. The foreshore south of Bluff faces directly south over Foveaux Strait toward Stewart Island and beyond. Light pollution from Bluff township is minimal - the town is small and the south-facing shore is away from the main settlement. At Kp 2-3, aurora australis appears on the southern horizon from Stirling Point, reflecting in the strait. The distance advantage over Invercargill is modest (27 km), but the proximity to Foveaux Strait gives a true ocean southern horizon with no land obstructions.
Toetoes Bay / Waikawa Point
Get directions ↗An exposed bay on the southeastern tip of Southland, south of the Catlins highway. The bay faces south-southeast over open Foveaux Strait. Bortle Class 2 conditions - no towns within 20 km to the south or east. The bay is reached via Waikawa Road from Fortrose. At night the area is completely dark and the southern horizon is unobstructed ocean. At Kp 2-3, aurora australis appears to the south and south-southeast from the shoreline. The combination of southern latitude (46.6°S geographic) and open ocean horizon makes this one of the more productive aurora positions in accessible Southland. The road is unsealed in sections - check conditions before driving at night.
Best time to see the aurora australis in Invercargill
Invercargill's aurora australis season runs from April through August, centred on the southern winter when nights are longest and darkest. The equinox months of March and September bring a boost in geomagnetic activity. Summer months bring too much twilight for aurora to show at this latitude.
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.
October through February brings persistent twilight that washes out the aurora australis. Strong events during these months remain invisible because the sky never gets dark enough.

How long to stay
For your best chance in March, plan at least 3 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.
