November is in full swing and we will soon begin the last month of the year.
But although the Christmas tree will soon be lit in the country’s towns and cities, it is not very reminiscent of winter weather in much of Norway.
Temperatures have been well above normal in the penultimate month of the year and this will likely continue for a while, meteorologist Siri Wiberg explains to Dagbladet.
Abnormally mild
So far in November, Blindern’s measurement station in Oslo only recorded negative degrees at night four times.
Low pressures are in line
At the same time, the vast majority of days have shown average temperatures well above normal in the capital, with variations from 0.3 to almost 10 degrees above the “normal” temperature for November, shows the summary of Yr .no
And it’s not just Oslo where it’s hot.
Meteorologist on duty at the Norwegian Meteorological Institute, Siri Wiberg, explains that all of southern Norway has been under hot air from Europe for a long time, and that we probably will for some time.
The reason is the location of the curves of the jet stream in Europe at the moment.
– If the jet stream goes too far south, we will be north of this and therefore it will be cold here. The way the “jet” is now means that only northern Norway has cooler air, but here it can also get milder towards the end of the week, says Wiberg.
He adds that temperatures can change as a result of cloud cover and different types of wind, and therefore the air may be somewhat colder than it currently appears.
– In western Norway, there has been a lot of precipitation in recent days and it will continue for the next 24 hours.
The worst will probably be in western Norway, explains the meteorologist, but adds that it comes in the form of rain.
“Normal” changes
Regardless of the development in the next few days, there is no doubt that November has been a very mild month.

However, exactly how abnormal it is depends on how normal is defined, explains Wiberg.
– Next year we will change the normal one, so that it adapts much more to the current meteorological situation. The standard we use today is adapted to the weather situation from 1961 to 1990 and is often no longer true. That this is changing now only shows that we are changing and that the weather is getting warmer, the meteorologist tells Dagbladet.
With its curves, the jet stream helps to control how high and low pressures move, but its movements have also changed as a result of climate change, the meteorologist explains.
– Changes in the weather have made him “hang a bit”. It gets looser in its movements, and then the high and low pressures hang a bit too, as we’ve seen now with the temperatures in November, Wiberg tells Dagbladet.
