The warm and humid summer air was replaced by thunderstorms and downpours in parts of Denmark on Sunday night.
While the Copenhagen area got off pretty easy with a thunderstorm that produced thunder and lightning but not huge amounts of rain, other parts of the country were pummelled by cloudbursts.
According to meteorology institute DMI, at least seven areas officially experienced a cloudburst, defined by over 15 millimetres of rain in less than 30 minutes. The western Zealand city of Kalundborg received up to 23 mm within a half hour, while the northeast Jutland village of Vestervig got 39 mm overnight, almost half of which fell within a 30 minute period.
DMI said that a total of 3,571 lightning strikes were recorded in Denmark over a 24-hour period.
The same wet weather was reported in southern Sweden and is expected to hit the Swedish capital of Stockholm later on Monday.
Before the rains moved in, Sunday temperatures topped 31C in Copenhagen and on the island of Bornholm, making it the hottest day of the year thus far. The mercury peaked at Bornholm Airport near Rønne, where a reading of 31.9C was recorded. In the capital, temps topped out at 31.6C.
The hot Sunday made life difficult for the tens of thousands of exhausted music fans who filed out of Roskilde Festival after many of them had been there for more than a week.

Had the festival not changed its main concert schedule to run Wednesday through Saturday instead of the traditional Thursday to Sunday, an all-time heat record could have been set this year. But because Sunday was not officially a part of the Roskilde schedule, the official heat record remains the 28.7C hit during the 1976 festival, a year made famous by Dr. Hook’s completely-nude performance.
