In fact, many of the roads in Norway are closed or otherwise inaccessible the rest of the year. The weather can be beautiful in the southern and urban areas.
In the northern parts of the country however, it can be very cold.
If you’re planning on traveling much farther north than Oslo, you will need a warm jacket, hat, gloves, etc.
Good to know before you travel
Passport and visa requirements On arrival in Norway, you must show a valid passport or other official document that satisfactorily establishes your identity and nationality.
Travelling with pets. Norway is one of few European countries where rabies is not found, and every precaution is being taken to maintain this status.
Dogs, cats and ferrets from all EU countries must have pet passports, ID marking and valid rabies vaccination. Dogs must also be given approved tapeworm treatment, minimum 24 and maximum 120 hours before arrival.
Small rodents, cage birds and rabbits must have valid import permits issued by the Norwegian Food Safety Authority.
What clothes should I pack? Whatever the season, the Norwegian weather is liable to change from day to day. So it is a good idea to bring a selection of items.
Your luggage should include some light clothes, items you can layer (that way you can add or remove layers depending on temperature), at least one warm jumper, waterproof coat and/or umbrella and comfortable walking shoes/boots/trainers.
If you go during the winter, you will need an overcoat, scarf, gloves and warm shoes/boots.
In autumn and spring, you may want to bring waterproof trousers and boots.
For the summer, lighten up, but remember that even summer evenings and nights can be chilly, particularly in the mountains.
