Denmark recorded its highest temperature on record on Saturday, the Danish Meteorological Institute (DMI) said, as the country was hit by a heatwave that has already plagued Europe.

DMI initially posted on X around 2:00 pm (1200 GMT) that “with 36.6C north of Odense, we have the warmest day ever since measurements began in 1874.”

With a sense of foreboding, it noted “the day isn’t over yet…”

“The record lasted exactly one hour,” DMI said in a later post, announcing the new record was set at 37.0C

“We’ve got a new heat record for the absolute highest temperature ever measured in Denmark. Today, 37.0 degrees was recorded both in Beldringe, north of Odense, and in Odum, north of Aarhus,” DMI meteorologist Rasmus Stoltze Hansen said in a statement.
