Think of Norway for a second! As people start pondering upon the word Norway, many think of ice, polar bears and snow! Some people enjoy the thought, while others start freezing just thinking about it. Before travelling to Norway it might be worth knowing that during December, January and February the average temperature is around -3 Celsius, which means it can get much colder than that during the night and on those really cold days. During summertime the temperatures can reach up to 33-34 Celsius during daytime if you are lucky, but the average temperature in Oslo in July and August is more like 16-17 Celsius.
