HOW TO READ THE NORTHERN LIGHTS FORECAST

The northern lights forecast can be found on en.vedur.is/weather/forecasts/aurora/, but it is a little hard to decipher if you’ve never seen it before. Our handy-dandy guide should make things a little bit easier.

Going on a tour?

There are many tours taking you far from the bright city lights for a better chance of seeing the aurora. These tours will be cancelled if there is no chance of seeing the lights. All major operators can be trusted to do this, first of all, because there is a high standard of professionalism in Iceland, but more importantly, because they lose money if they take you out needlessly – most of them promise to take you out again for free if you don’t see anything.

The Colours

White means no clouds while dark green means very cloudy. The different shades of green then mean more, or less, cloudy.

The numbers

The numbers are a combination of how likely it is for the lights to be active and how active they will be. Don’t be discouraged if the number is low, it’s actually very rare for the number to be higher than five. Also, take the scale with a grain of salt; a low number doesn’t mean that they won’t come out or won’t be impressive, and a high number isn’t a guarantee that they will be glorious all through the night.
