“I have never before seen a month with such big temperature jumps,” climate researcher Jostein Mamen is quoted as saying in a Twitter post by the meteorological agency.
Årets mai er den varmeste som er registrert på 100 år. – Jeg har aldri sett en måned med et så stort sprang i temperaturavvik noen gang, sier klimaforsker Jostein Mamen.

New record temperatures were set at 73 different recording stations across the country, news agency NTB reports.
Temperatures have been recorded since 1900.
At the Norwegian Meteorological Institute offices in Blindern near Oslo, the average recorded temperature for the month was 16.1 degrees, the highest ever measured by a Norwegian station in May.
Friday, the first day of June, has continued the bathing-friendly weather into the new month – water temperatures are reported at over 20 degrees from the Swedish border to the western county of Rogaland.
