Many factors mean that the Northern Lights can’t always be seen. In summer, for example, the northern lights aren’t visible, as the light of the sun will be too strong. Even in winter, they won’t be on display all the time. Sometimes the night sky will be cloudy, or the light of the moon will be too bright. At other times, the aurora just won’t be strong enough to be visible.
It is recommended to book your Northern Lights tour for the first night of your stay. In case your tour is cancelled due to bad weather, you will have time to reschedule for an alternative date.
