The northern lights season starts every year in September and is until mid-April. There isnât one particular month better than the other, as it is impossible to predict when the northern lights will decide to show up and how the weather is going to be.
The northern lights are always present, but winter is usually the best time to see them, due to lower levels of light pollution and the clear, crisp air. September, October, March and April are some of the best months to view the aurora borealis.
