Norway has seasons
Many people have the misconception that Norway is always very cold. While it is true that Scandinavia has hard winters, this is not the case all year. Norway has four seasons: winter, spring, summer, and fall. If you're considering a trip to Norway, keep this in mind.
Some sites are only open during particular seasons, while some hikes are closed in the winter. Determine which season is best for visiting a given destination if that is your primary goal. Another thing to remember is that the weather fluctuates dramatically from season to season.
When traveling to Norway, make sure you carry extra clothing because it gets cold! It's always a good idea to keep an eye on the weather forecast and make sure everything is open during your visit by doing some research. In the summer, it can get fairly hot, so bring appropriate clothing.
