Do you remember when it rained more in Oslo than in Bergen last year?

Last year was the coldest year in Norway since 2013, but was still among the 30 warmest years since 1900.

There were several downpour episodes this summer. Here from a very wet Oslo day on 9 July.

This year’s weather accounts are ready from the Meteorological Institute, and all protection nests can gas themselves in detail.

Here are some of them:

In the last 120 years, there has never been a wetter October in Bergen than last year. But in May, it poured more on the people of Oslo than in the minds of the people of Bergen.

– 2021 was a fairly normal year, quite on average for the last 30 years. But there were also great contrasts with several extreme weather episodes and several records, said state meteorologist Rafael Escobar Løvdal when summing up Wednesday morning.

Last year was colder than any year since 2013, but was still among the 30 warmest.

In 2021, the average temperature in Norway was at the new normal, while precipitation was 10 percent below.

The current “normal” is the average of all weather for the 30-year period 1990 to 2020, while the previous one, which applied until a year ago, was from 1960 to 1990.

Extreme weather “Frank” struck on 21 and 22 January and created chaos in car and boat traffic. Here from Helgelandsbrua by Sandnessjøen where it blew 30 meters per second.

Dry and cold winter

January 2021 was the coldest January in ten years with a monthly temperature for the whole country of 3.3 degrees below the new normal.

In the Inland and Viken counties, some stations had a deviation of 8 to 10 degrees below normal.

Precipitation was only 55 percent of normal, making January 2021 the driest since 2010. In northern Norway it was particularly dry, and a number of stations had less than 10 percent of normal precipitation. In Viken, a couple of stations received up to twice the normal amount of precipitation.

On 21 and 22 January came the extreme weather «Frank», with strong icing and strong gusts of wind. In Sandnessjøen, the strongest gusts were measured at 47.3 meters per. second.

Although February was also cold, the month offered heat records, including in Kjevik and in Asker with 16.3 and 13.8 degrees Celsius, respectively.

The winter of 2021 as a whole was 0.7 degrees colder than normal, but one degree warmer than the old normal.

Warm spring throughout Norway

The mild weather began at the end of February, and several local heat records were set in southern Norway.

March ended almost two degrees above normal and was warm throughout the country. In Lier, it was measured over 20 degrees, which has only happened twice before in Norway so early in the year.

Eastern Norway had a wet May, and in Oslo this month was wetter than it was in Bergen.

Seventh hottest summer

Summer is the seventh warmest as recorded since the Meteorological Institute started measurements in 1900. Several places had a record number of days with 20 degrees or more. However, there were not many measurements above 25 degrees.

In Notodden, the temperature was over 20 degrees almost every day in June, July and August.

In the north of the country it was hot in early July. Banak in Finnmark set a county record of 34.3 degrees on 5 July.

Otherwise, it was cool and record wet in some areas in Nordland, Troms and West Finnmark.

In terms of precipitation, the summer offered great contrasts.

On July 29, six torrential rain records were set on Tjøme in old Vestfold county. Among other things, 50.7 mm of precipitation fell in 30 minutes, and 78.5 mm in one hour.

But in Western Norway it was dry, and in Bergen, since 1900, there has never been a drier period from January to September than in 2021.

The cloud of dust stood after the tractor that plowed on Gjerdrum. September was very dry all over the country, and little precipitation is a contributing factor to the winter’s high electricity prices.

Crush dry and deep wet autumn

The autumn started very dry with drought records in several places in southern Norway. September was drier than normal throughout the country.

Drammen had the warmest September day ever measured in Norway, with 28, 6 degrees on 8 September.

October was the third wettest since 1900, and in Bergen there was more than twice as much precipitation as normal at the Florida station. This is the highest monthly rainfall measured in the center of Bergen regardless of the month.

November was also wet, and especially in Central Norway, where several old precipitation records were broken. Østås in Hegra received 65.3 mm of precipitation on 23 November, while the previous record was 42.9.

Warm the world

2021 looks set to be the sixth or seventh warmest year measured globally.

Extreme levels of rainfall in Germany and several countries led to major floods and more than 200 deaths.

2021 was the warmest year ever measured in Europe. This led to several heat waves and major forest fires in Russia and the Mediterranean.
