Aurora australis in South Africa tonight
Aurora australis over Cape Point, South Africa - southernmost headland facing open ocean, 42°S magnetic latitude, Kp 7 threshold.
How the sky looks right now
Live Kp index from NASA & NOAA, mapped to what it means across South Africa.
Low activity expected. Solar conditions are currently quiet. Chances of aurora visibility are low tonight.
How far the glow reaches
At Kp 1, the auroral oval reaches ~76°S - covering every South Africa town within range.
7-day outlook for South Africa
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, so tonight's activity does not carry forward. For a longer-range view based on solar rotation, see NOAA's 27-day outlook.
Forecasts beyond 3 days are lower confidence - check back nightly as the outlook firms up.
Aurora visibility by town
Each spot lights up at a different Kp threshold thanks to its latitude. It comes down to the clouds.
Kap the penguin's tip: South Africa sits between 22° S and 35° S - far enough from the southern auroral oval that you need a major geomagnetic storm to see anything. G4 and G5 events, Kp 8 and above, have produced aurora visible from the Western Cape. The September 2023 and May 2024 storms were seen from Cape Point. These events are rare - once or twice a solar cycle - but they do happen.
Best months for South Africa (Cape Town)
March, April and May average the most aurora nights. July and November to February count zero: across the fifteen years, no night in those months reached this threshold. Aurora in South Africa is event-driven rather than seasonal. Monitor NOAA G3+ storm alerts.

Threshold · Kp 8Why South Africa stands out
South Africa is at the extreme northern edge of where aurora australis ever reaches. At 42–43°S magnetic latitude, the threshold is Kp 7–8 - a G3–G4 geomagnetic storm. These events occur a handful of times per year during solar maximum but are not guaranteed annually. When they do occur, the conditions must also align: clear skies, dark site, and the storm peaking during nighttime hours in South Africa.
Sutherland in the Karoo is the standout dark sky site. The South African Astronomical Observatory operates there at 1,798 m elevation with Bortle 1–2 skies and some of the best atmospheric stability on Earth. Cape Point gives a dramatic south-facing headland position over open ocean. Both sites confirmed aurora australis during the G5 storm of May 2024 - a benchmark for what is possible from South Africa during extreme events.
March and September - the equinox months - are statistically the most geomagnetically active periods of the year. These are also transitional seasons with reasonable night length and clearer weather than winter. The June–August winter gives longer dark nights but is not geomagnetically enhanced. Monitor space weather alerts during any G3+ storm watch.

How often does the aurora appear in South Africa?
Average nights per month the Kp reached Cape Town's threshold, from 15 years of geomagnetic data (2010–2024).
Based on geomagnetic data 2010–2024. South Africa needs G3+ storms - events are infrequent but the equinox months (March, September) provide the best probability. Sutherland's Bortle 1-2 skies give the best sensitivity.
Plan your trip to South Africa
Best window
March and September for equinox geomagnetic activity peaks. Drive to Sutherland in the Karoo (3 hours from Cape Town) for Bortle 1-2 conditions at 1,798 m when a G4+ storm is forecast during nighttime hours.
Storm-dependent viewing
Aurora in South Africa is exclusively storm-dependent. Set NOAA G3+ storm alerts. When a severe storm is confirmed during South African night hours, drive to Sutherland or Cape Point immediately - events can be unpredictable.
