This is a tricky one, as I believe that there is actually one place on Earth that stands out as the best place on the planet to see the auroras. Lots of destinations like to market themselves as the “best” place to see the northern lights but the simple truth of the matter is that there are a few conditions that must be present to have a successful aurora sighting.
The first is that you almost always need to be above the Arctic Circle or below the Antarctic Circle, in the aurora zone in order to increase the odds of seeing the lights. The second factor is that you need a clear sky. The truth of the matter is that weather patterns above the Arctic Circle or below the Antarctic Circle tend to be very unstable with lots of heavy weather including snow, wind, rain, blizzards, etc. Taking both of the previous factors into consideration, there is ONE location that is above the Arctic Circle and has a very high likelihood of clear skies. This location is Abisko National Park, Sweden. The reason that Abisko stands out as the clear winner is the fact that it is right in the middle of a microclimate that leads to more clear skies than any other location in the aurora zone. This microclimate known as the “blue hole of Abisko” gives travelers from all over the planet the best possible chance of success. But you don’t have to take my word for it — you can read more about the blue hole here, and you can keep an eye on the sky with Lights Over Lapland’s array of still, HD and VR webcams which have been keeping an eye on the sky for more than a decade here.
