We’re sometimes asked for statistics regarding the frequency of displays of the Aurora Borealis in the destinations we feature and unfortunately, we have to reply that statistics on the subject are pretty meaningless. Basically, across the Auroral oval, the Lights appear around 200 times per year regardless of whether you are in Finland, Sweden, Norway or Iceland.
However, it is impossible to make any long term predictions as to which of the 200 days will yield results and which of the remaining 165 (or 166 during a leap year) will not.
