Highest temperatures expected in Denmark during this week's heatwave: locate hottest spots
Heatwave to Sweep Across Denmark, Highest Temperatures Forecasted in North Zealand and Bornholm
A heatwave is set to engulf Denmark over the next few days, with temperatures peaking on Thursday. According to the Danish Meteorological Institute (DMI), the hottest regions will be North Zealand and Bornholm, where temperatures could soar to around 30°C.
The heatwave aligns with a pattern of heatwaves in Northern Europe, where even typically cooler areas like Denmark are experiencing significant heat spikes amid broader regional heatwaves affecting Scandinavia. In early July 2025, Denmark recorded temperatures as high as 34.0°C, indicative of the potential for intense heat in various parts of the country.
On Wednesday, temperatures will reach 27 to 28 degrees Celsius, with the warmest spots expected in Jutland, specifically Skive on the west coast and the island of Mors. Thursday will see temperatures peak at around 27 to 28 degrees, with the Copenhagen area likely to be the hottest.
However, a new front moving over western Jutland on Thursday will lead to lower temperatures in the region, with the west coast cooling considerably by Friday. The peak temperature on Friday is forecasted to be around 20 degrees, with some areas only reaching 17 or 18 degrees.
In contrast to dry conditions on Wednesday, rain is forecast in Jutland, starting in the west at around 9am and moving north. Rain may persist on Friday, the final day of the heatwave, in the form of scattered showers, which may be heavy in places and accompanied by thunder.
The DMI defines a heatwave as a three-day period with an average highest temperature over 25 degrees Celsius. For a heatwave to be classified as a hedebølge, the average highest temperature for the three days must exceed 28 degrees Celsius. The upcoming heatwave in Denmark could potentially qualify as a hedebølge, but this will depend on the exact temperatures recorded over the three days.
Despite the rain, most of the country will stay dry during this period. Lolland and Falster could potentially break the 30-degree mark locally, with temperatures of 28 to 29 degrees Celsius expected on southern islands Lolland-Falster and Bornholm on Thursday.
The next 72 hours in Denmark are forecasted to be warm, with the heatwave expected to end on Friday. As the heatwave subsides, cooler temperatures and potentially rainy conditions are expected to return, providing much-needed relief from the intense heat.
