Whether tonight is worth a look south for the aurora australis — NOAA's space-weather model, the cloud forecast and the hours of darkness over Denmark's south coast.

Quiet tonight
Activity looks low. A faint glow is always possible, but tonight isn’t a likely one.
Cloud is likely to block the view tonight.

Denmark faces the Southern Ocean, which is exactly what an aurora chaser wants — but at this latitude the aurora australis sits low in the southern sky, not overhead. It takes a strong geomagnetic storm (roughly Kp 6 or more) for a glow to show from the south coast, and a severe one for the tall red and green beams people photographed here in May 2024.
From the WA south coast most displays start as a faint grey-pink smudge to the naked eye. A phone or camera on a long exposure picks up the colour well before your eyes adjust — if the photo shows pink or green above the southern horizon, stay out; it may build.
June to August brings Denmark's longest, darkest nights, and the current solar cycle is still near its 2025–26 peak, so strong storms arrive more often than in an average year. The two together make this the best stretch in a decade to catch the aurora from the south coast.
Updated 2 July at 15:15. The aurora is famously unpredictable. This blends NOAA’s space-weather model with the cloud forecast and the hours of darkness — it can point you to a promising night, but it can’t promise a show. Official forecast: sws.bom.gov.au.
