Siglufjörður lies at 66.15° N in North Iceland, about 45 km south of the Arctic Circle. With a geomagnetic latitude of about 67.0°, it sits under the auroral oval: even quiet nights (Kp 1–2) can bring aurora overhead. Over the long term, a dark, clear night here has roughly a 75% chance of some visible aurora.

Nights with at least two hours of real darkness run from late August to mid-April. Around midsummer the sun does not set at all (mid-June to early July), and the light nights either side rule out aurora. Around the winter solstice the sun is more than 12° below the horizon for about 15.5 hours a day.

Clouds decide most nights. Long-term records for Lake Mývatn, 106 km away, show night-time cloud cover averaging 79% in September, the clearest month of the season, so roughly 21% of nights are clear then. Check the cloud layers in the hourly forecast above: a short drive can make the difference when cloud is patchy.
