Seasons and Climate
The city is warmer than most other places located on the same latitude, due to the warming effect of the Gulf Stream. From 20 May to 22 July, the midnight sun is a special experience, with daylight 24 hours for two months.
Between 21 November and 21 January, the sun disappears below the horizon and the polar night sets in. It is not completely dark in the middle of the day, however, and the light and colour in the sky during that time of year is very special – it is called the blue twilight.
Temperature in September can vary between high of 12°C and low of 4°C. The winter in Tromsø is not especially cold. The average January temperature is -4°C. There is often a lot of snow and the relatively mild winter is perfect for outdoor activities.
