How to read this forecast

The next 24 hours use calculated local darkness and a retained aurora activity heuristic. They are not a measured or statistically calibrated chance of seeing aurora. Aggregate cloud cover is held constant unless a timed weather forecast is available.

Frequently Asked Questions

Can you see the Southern Lights in Bariloche?
Aurora Australis may be visible from Bariloche when geomagnetic activity is strong, the sky is dark and clear, and the southern horizon is open. A Kp value near 7–9 is a useful guide for this location, not a guarantee.
What is the best season for the Southern Lights in Bariloche?
The practical dark-sky season in Bariloche runs from March through September, with the longest nights usually from May through August. Aurora can occur year-round whenever geomagnetic activity and darkness overlap.
Where should I look for Aurora Australis near Bariloche?
Choose a dark site away from city lights with a wide, unobstructed view toward the southern horizon. Check cloud cover, moonlight and local access conditions before leaving.
What Kp index is needed in Bariloche?
The Kp needed varies with magnetic latitude and storm geometry. Around Bariloche, Kp 7–9 is a planning guide; the solar-wind direction, especially southward Bz, can change the actual result.
Do the equinoxes improve Southern Lights chances?
Geomagnetic activity can be more favorable around the March and September equinoxes, but there is no guaranteed equinox display. Darkness, clear skies and an active auroral oval must still coincide.
