Aurora tonight in Reykjavik

Can you see the aurora borealis from Reykjavik?

Reykjavik sits close enough to the auroral oval that the northern lights are a routine winter occurrence rather than a special event.

Reykjavík is the world's northernmost capital city, sitting at magnetic latitude 64.5°N — enough for Kp 2 displays to show on the northern horizon. It is also a small city with a very bright centre, so the practical question here is never whether the aurora is strong enough, but whether you are standing somewhere light does not wash it out.

When to look: the Reykjavik aurora season

Work from **5 Sep** to **7 Apr**: that is the stretch in which Reykjavik gets a properly black sky, 215 nights in all. Outside those dates the sun never drops the full 18° below the horizon, so some twilight stays in the sky whatever the geomagnetic forecast says. The counter-season is just as clearly defined: from about **8 Apr** to **4 Sep** (150 nights) the sun never gets 18° below the horizon, so the sky never reaches full darkness, and between roughly 25 Apr and 17 Aug it does not get properly dark at all — no display, however strong, is visible in that stretch.

The dark half of the year at Reykjavik delivers a genuinely black sky, with the sun 49.3° below the horizon at its deepest. The bright half is the trade-off: from around 8 Apr to 4 Sep the sun stays above 18° below the horizon, and nothing short of a major storm has a chance.

Where to go in Reykjavik

Head for the western edge of the city, where the built-up area ends and the sky opens toward the north and west. Anywhere on the coast away from street lighting works; the further from the centre, the more structure you will see.

Direction matters as much as darkness. The display will be over the magnetic pole, which from Reykjavik means the northern sky — so pick a viewpoint with nothing between you and that horizon, and put any streetlight behind you. Tonight's "best window" figure above is the first hour where cloud falls below about 40% inside this latitude's dark period.

What Kp do you need in Reykjavik?

Kp is a planetary number, and the only way to read it usefully is against this city's own threshold. For Reykjavik that threshold is Kp 2, set by a magnetic latitude of 64.5°:

The most common reason people miss a display at this latitude is timing rather than strength: a Kp 2 night is enough, but substorms come and go inside a single Kp interval, so a 20-minute gap in your attention can be the whole show. Check the sky every 20–30 minutes rather than once.

How tonight's answer is calculated for Reykjavik

Tonight's verdict for Reykjavik weights five inputs: the live Kp forecast measured against this city's own Kp 2 threshold (35%), night-average cloud cover at 64.15°, -21.94° (25%), moon illumination (15%), the astronomical darkness window computed for this latitude (15%), and light pollution at Bortle class 5 (10%).
