Northern lights forecast for Reykjavík

What the forecast numbers mean

Seeing the aurora comes down to activity, clear skies and darkness lining up. First, activity, measured on the Kp scale from 0 to 9. Reykjavík sits close to the aurora zone, so even Kp 2 or 3 can give a good show on a clear, dark night. Kp 4 and above means higher geomagnetic activity, though a display is never guaranteed.

Then the sky has to be clear enough. Clouds are the usual reason people miss the aurora, though you don’t need a cloudless sky; gaps in the clouds are often enough. And it has to be dark, with the sun well below the horizon. Around midsummer the nights are too bright, and dark enough nights return in late August.

We combine all of that into one verdict per night. The aurora doesn’t read forecasts, though. It can turn up out of nowhere on a so-so night and vanish ten minutes later.

When is the best time to see the northern lights in Iceland?

The season runs roughly from late August to mid-April, when the nights are dark enough. The lights usually show between 22:00 and 02:00, but they can appear any time it’s dark. What matters is a dark sky with gaps in the clouds, so check the cloud forecast as well as the activity. A bright full moon makes faint auroras harder to see, although strong ones still shine through.

Northern lights in Reykjavík, month by month

• Late August to October: the season begins. Nights are getting darker, the weather is often milder, and lakes and the sea reflect the lights.
• November to February: the longest nights, so the most hours of darkness to catch a display. Also the most storms and cloud, so dress warmly.
• March to mid-April: still dark enough in the evenings, often with calmer, clearer spells. The season ends as the nights get light.
• May to mid-August: too bright. Around midsummer the sun barely sets, so aurora watching isn’t possible.

Can you see the northern lights in Reykjavík?

Yes. With moderate or strong activity and a clear sky, the aurora can be right above the city. City lights wash out the faint ones, though, and a 10 to 20 minute walk or a short drive to somewhere darker makes a big difference.

Where to see the northern lights in Reykjavík

If you’re staying downtown, start with the seafront path from Harpa to Höfði house and look north over the bay towards Mount Esja. Klambratún park works when the aurora is strong, and Laugardalur, the big green valley to the east, has open spaces away from the brightest lights. Öskjuhlíð, the wooded hill around Perlan, has darker paths.

For the darkest sky within the city limits, go west to Grótta lighthouse at the tip of Seltjarnarnes, with nothing but sea to the north. The causeway to the lighthouse can be cut off at high tide, so check the tide and take care in the dark.

Before you head out

• Dress for a long wait: warm layers, a hat, gloves and good shoes. Pavements can be icy.
• Give your eyes 15 to 20 minutes to adjust to the dark, and keep your phone screen dim.
• Phone cameras in night mode often pick up more colour than your eyes do. Hold still, or rest the phone on something.
• Check the forecast again during the evening. Clouds move fast here, and a cloudy forecast can clear.
• Driving? Never stop on the road or the hard shoulder to look. Park somewhere safe.

Planning the rest of the evening? Have dinner first; our things to do in Reykjavík has ideas. Or spend the waiting time in a geothermal pool and keep an eye on the sky.
