Denmark officially experienced its first meteorological summer day of the year on Saturday as temperatures in Borris, West Jutland, exceeded 25 degrees Celsius, according to the Danish Meteorological Institute (DMI). This marks the latest arrival of the first summer day in 15 years.

The high temperature was recorded on Saturday afternoon. The last time Denmark experienced a later first summer day was June 28th, 2010. Prior to that, in 2004, the temperature did not reach over 25 degrees until July 30th.

Several locations in southern Jutland also reported high temperatures on Saturday. Store Jyndevad reached 24.9 degrees, while Billund recorded 24.3 degrees.

However, the warm weather is expected to be short-lived. DMI forecasts an approaching front bringing rain and thunderstorms to West Jutland during the evening hours.

The front is expected to move eastward over Jutland and Funen throughout the evening and night. Sunday morning will bring a mix of clouds and showers, potentially with thunder, to these regions, while eastern parts of the country will experience sunshine. The heaviest showers are predicted to hit Jutland and Funen first, with Zealand also experiencing them in the afternoon.

Sunday’s temperatures are expected to range from 18 to 25 degrees Celsius, with the warmest temperatures in the eastern part of Denmark.
