In several places in eastern Norway, there was up to three times more rainfall than normal in October. In Nordland, on the other hand, it was unusually dry.

In October, a precipitation of 134.4 millimeters was measured at the Tunhovd measuring station in Nore and Uvdal. Never before in the 125-year life of the station had so much October rainfall been recorded. Image is from Pålsbufjorden. Photo: Lise Åserud / NTB

Earlier, it was clear that for the first time since 1993, more rains were recorded in Oslo than in Bergen in October.

In October, five precipitation records were set at five locations in Viken and Vestfold and Telemark. The biggest increase since the previous record was seen by Veggli at Rollag at Viken, which finished at 174 millimeters, 24.9 millimeters more than the previous record of 2014.

Also noteworthy is Tunhovd in Nore and Uvdal. Never before in the 125 years of the station’s life had so much precipitation (134.4 millimeters) fallen in October.

Second in a row for Jan Mayen

At the other extreme, nine stations have a new low record. Two in Stryn in western Norway, three in Nordland and two in Troms and Finnmark. The last record belongs to Jan Mayen. Despite the measurements here dating back to 1921, the previous record was set in 2019.

Nationally, rainfall was just below normal (95 percent), while the monthly temperature was 1.5 degrees above normal. It is the 15th warmest since 1900.

Nordland had multiple seasons with less than 25% of normal rainfall, and it was the country’s two northernmost counties that had the relatively hottest temperatures. Individual stations had deviations of up to 3 degrees above normal.

Into winter

Lindesnes Lighthouse and Kvitsøy were the warmest places in the country with an average temperature of 11.2 degrees in October. The highest maximum temperature, 21.4 degrees, was in the North Sea municipality of Tingvoll on the first day of the month.

If we look at the colder places, there are many signs that we are approaching the white season. Gamanjunni at Kåfjord in Troms was the coldest (-2.7 degrees) during the month, while Folldal and Kautokeino measured -18.7 degrees during October.

Thus, there was a 40.1 degree difference between the warmest and coldest kingdoms experienced in the 10th month of the year.
