Norðurljósa spár geta breyst því sólin er óútreiknanleg. Sólvirkni einsog sólblossar og vindar eru sífellt að breytast og það hefur áhrif hvar og hvernig norðurljósin birtast. Veðurfar á jörðinni hefur líka mikil áhrif, sérstaklega skýjafar. Þess vegna skiptir máli að skoða rauntíma spár og vera þannig einu skrefi á undan fyrir bestu norðurljósa upplifunina.

Já! Fylgstu með Leirvogur segulvirkni, sem metur segul-truflanir yfir Íslandi. Þegar línuritin sína aukna hreyfingu þýðir það að sólvindar eru að hrista segulsvið jarðar - sem endar oft með norðurljósum. Að fylgjast með þessu ásamt Kp skala og raun-tíma spám gefur þér bestu möguleikana á að sjá norðurljós.

The Kp Index is a reliable tool for measuring geomagnetic activity and predicting the Northern Lights, but it’s not perfect. It provides a general forecast averaged over 3-hour periods, so conditions can change quickly. For the most accurate predictions, combine the Kp Index with real-time data on solar activity, cloud cover, and local magnetic disturbances.

The best months to see the Northern Lights in Iceland are from September to April. During this period, the nights are longest and darkest, creating ideal conditions for aurora viewing. The peak months are October to March, when the skies are darkest, and solar activity is often stronger. Just remember to check the weather for clear skies.

A low Kp number (0–2) means the Northern Lights will likely be faint, appearing as a soft, pale glow – often resembling thin clouds – and are usually only visible in far northern areas. A high Kp number (5–9) brings vibrant, dynamic displays with bright greens, purples, and even reds dancing across the sky, sometimes visible much farther south.

það er mjög ólíklegt að sjá norðurljós á Íslandi yfir sumartímann. Frá Maí til Júní upplifir Ísland næstum því 24 tíma af dagsljósi, miðnætursólin gerir það að verkum að himininn er of bjartur til þess að sjá norðurljós. Besti tíminn til að sjá norðurljós á Íslandi er frá september fram í apríl. Þá er myrkur og næturnar eru nógu langar.
