Less Ice in the Arctic Signals a Colder Winter in Norway. Meteorologists Warn of Cold Waves

According to data from the Norwegian Meteorological Institute, the average temperature in the country since the beginning of the year has remained 1.6 degrees above normal. On an annual scale, this means an increase of 51 percent compared to the average temperature of 3.1 degrees.

"All indications are that 2025 will be the warmest year in the history of measurements," said meteorologist Magnus Ovhed. The expert emphasizes that high temperatures have persisted for many months and significantly exceed previous records.

Norway is currently experiencing exceptionally warm days. Winter may surprise with several cold waves. "Winter will likely start off mild, but we also expect a few cold periods," Ovhed announced.

The key factor is the small amount of ice in the Arctic. When its level drops, the air in the north does not cool as intensely, which can weaken stratospheric winds. As a result, cold air masses have a greater chance of reaching Norway and the rest of Europe.

Seasonal forecasts from the Meteorological Institute indicate that from November to January, temperatures in most of the country may be above normal. In the second part of winter, however, sudden drops in temperature may occur. "These are indicative forecasts, so alongside cold episodes, there will also be milder periods," Ovhed explained.

Currently, in southern Norway, thermometers show over 15 degrees. In the northern regions, especially in Finnmark, the first snowfall is expected at the end of the week.

Phenomena observed in the Arctic are increasingly affecting weather conditions across Scandinavia. The lack of ice cover in northern waters may mean milder winters in the far north and, at the same time, colder periods in southern regions.

If forecasts regarding wind patterns and ice levels are confirmed, stronger frosts may not arrive until the later part of the winter season.
