Climate zone: arctic polar zone

The climate in Svalbard is not really suitable for petted US Westcoasters or Central Europeans. It is mostly cold and in winter months the mercury column won't reach anything above freezing point. In the cold season even the maximum temperatures are well below zero. Due to the warmer temperatures the best time for traveling is from June to September. Nearly unattractive for tourists are the cold months from November to May.

Long-term development of temperatures from 1981 - 2018

In the years 1981 to 2018 there were only 2 weather stations in the whole country, which reported continuous temperature values (Jan Mayen, Svalbard). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was Juli 2016 with 7.8 °C. Dezember 1988 was the coldest month with an average temperature of -15.6 °C.

The average annual temperature was about -3.5 °C in the years after 1981 and about 0.0 °C in the last years before 2018. So in less than 38 years it has increased by about 3.5 °C. This trend only applies to the selected 2 weather stations in Svalbard. A considerably more comprehensive evaluation of the global warming has been provided separately.
