Weather Overview
Typically a rainy month. You won’t see snow anywhere, though the weather is starting to cool. There are the last bits of summer in the first half of the month, and temperatures in southern Norway are still pretty good. Above the Arctic Circle, autumn has arrived and the colours start to turn orange. September can also be an unpredictable month, and the weather can change rapidly.
The Northern Lights are visible in September.
Tourism
The tourism season starts to die down in September, with the last groups typically doing their last tours around the middle of the month. The attractions tend to switch to their shorter winter hours by the end of September, but each one is different.
It is possible to see the Northern lights in September, and it’s a good month for road tripping because snow hasn’t blocked the roads yet. It feels comfortable to get around and hunt the northern lights yourself.
Events
- The Bergen Food Festival:
During the festival local food producers and chefs work together to create amazing food experiences. The food focuses specifically on the west coast of Norway and there’s a great selection of local cheese, meat, seafood, honey, vegetables, fruits, berries, cider, bakeries, and other exciting produce. At the same time and same place, the Norwegian Cider Festival takes place. What a perfect combination!
