About This Forecast
Northern Lights Forecast Norway provides real-time aurora borealis predictions for 50 places across Norway. Our goal is to help tourists and locals alike find the best time and place to see the northern lights.
Who publishes this site?
Aurora Norway is the publisher of this forecast and its travel guides. Articles use the Aurora Norway Editorial Team byline. Our workflow uses AI-assisted research and drafting with automated quality checks; the byline does not claim a named human expert or first-hand experience.

How It Works
We combine three data sources to help you compare the ingredients for aurora viewing across Norway:
NOAA OVATION Aurora Forecast
NOAA's OVATION model provides a short-term estimate of aurora activity overhead. It does not include local clouds or guarantee that an observer will see a display. We check for new data every five minutes and show the source timestamp.
Kp Index (Planetary K-index)
A measure of global geomagnetic activity on a 0-9 scale. Higher Kp generally indicates aurora activity extending further south; it does not guarantee a better display at every location. We fetch real-time Kp data from NOAA's Space Weather Prediction Center.
Norwegian Weather Data
Cloud cover is critical for aurora viewing. We fetch live weather forecasts from Yr (Norwegian Meteorological Institute / NRK) for the top aurora cities, so you know if skies will be clear enough.
Understanding the Numbers
Activity (NOAA): The raw probability of aurora overhead at that location, from the OVATION model. This doesn't account for weather or darkness.
Cloud cover: The percentages on the map describe local forecast cloud cover, not sighting odds. Our evening outlook combines cloud forecasts, approximate darkness and current activity. Tomorrow shows weather and darkness without reusing current aurora activity.

When to See Northern Lights in Norway
Dark evenings make September to March the main viewing season. Late August and April can also work, depending on latitude and date. Darkness varies with season and location, so use the local viewing window instead of a fixed clock time. Clear skies and aurora activity must coincide; no Kp threshold guarantees a sighting.
Best Locations
Northern Norway (Troms and Finnmark) offers the best chances, with cities like Tromsø, Alta, and Hammerfest sitting directly under the auroral oval. However, during strong geomagnetic storms (Kp 5+), aurora can be visible as far south as Bergen, Oslo, and even Kristiansand.
