What the sun is sending us
The aurora starts 150 million km away. These readings come from satellites a million km towards the sun — about an hour's warning of what reaches Iceland.
Fast solar wind and a southward (negative) Bz open the door — that's when the aurora really dances. Last 6 hours shown under each reading.
The best places to see it
Aurora activity, cloud cover, darkness, moonlight and light pollution combined, hour by hour. Press play to watch the night unfold.
Tonight at Þingvellir
Tap a place on the map to change it. Green is your chance of seeing the aurora, grey is cloud, and the dark band is when it's dark enough.
Aurora activity forecast
NOAA's planetary Kp forecast in 3-hour steps. In Iceland, even Kp 2–3 can give a beautiful show when the sky is clear and dark.
How to actually see it
Get away from the lights
Even 20 minutes outside Reykjavík makes a huge difference. Faint aurora disappears in street light.
Clouds matter most
A clear sky with Kp 2 beats a cloudy sky with Kp 5. Follow the gaps in the clouds — that's what the map is for.
Be patient
The aurora comes in waves. It can be quiet for an hour and then fill the sky for ten minutes. Give it time.
Let your eyes adjust
Give it 15–20 minutes in the dark and keep your phone screen dim. Your eyes see more than you think.
Camera settings
Tripod, wide lens, ISO 1600–3200, 5–10 second exposure, focus on infinity. Phones: use night mode and hold still.
Dress for standing still
Warm layers, hat, gloves and good shoes. It's colder when you're waiting than when you're walking.
How this forecast works
Viewing chance
For every place and hour we combine five things: aurora activity (NOAA's OVATION model for the next hour, then the Kp forecast with Iceland's position under the auroral oval), cloud cover (low cloud counts most), darkness (the sun at least 6–12° below the horizon), moonlight and light pollution.
It's an estimate, not a promise — the aurora can appear or fade within minutes.
