Although summer in Denmark has been historically warm this year already, it is now about to get hotter.

High daytime temperatures and ‘tropical’ conditions of over 20 degrees at night are forecast from the middle of this week onwards, says the Danish Meteorological Institute (DMI).

“From Wednesday it looks like daytime temperatures will be between 25 and 30 degrees and maybe up to 33 degrees locally,” DMI duty meteorologist Dan Nilsvall said on Monday.

“Thursday and Friday will be particularly warm in Jutland,” Nilsvall added.

Monday will see temperatures of between 22 and 27 degrees, albeit cooler in coastal areas, while Tuesday will be a little warmer at 25-30 degrees.

“Wednesday, Thursday and Friday will bring possible local showers during the afternoon, possibly with thunder,” Nilsvall said.

Nighttime temperatures will also be warm.

“There further into the week we get, the more likely it becomes the nights will be tropical,” the meteorologist said.

For a night to be classified as tropical, the temperature must remain above 20 degrees Celsius throughout a 24-hour period.

“The temperature on both Wednesday and Thursday nights will be around 20 degrees,” Nilsvall said.

A heatwave is defined by an average temperature of 28 degrees or more in over half of the country for three consecutive days.

Many in Denmark are now desperate for rainfall – not least farmers whose crops are threatened by the dry weather – but little precipitation is forecast for the coming week.

Sunday was the 50th summer day in Denmark this year, defined as a day in which temperatures exceed 25 degrees Celsius in at least one location in the country.

How much will it snow in Denmark this weekend?

Winter weather arrived in spectacular fashion to coincide with the beginning of December this week. The weekend could bring more snow to parts of the country but probably less disruption than recent days.

Recent snowstorms disrupted North Jutland in particular and Denmark in general, and more cold weather can be expected this weekend albeit severe, according to forecasts.

“We won’t see the Ragnarok-like weather we’ve seen in some places recently again this weekend, but it’s now winter weather and it has also snowed in several places overnight,” said meteorologist Frank Nielsen of the Danish Meteorological Institute (DMI).

Cold weather on Friday and a low front across the North Sea will bring clouds and precipitation across Denmark from the west, Nielsen said.

That will materialise as cold rain or sleet in many areas but probably snow in North Jutland, he said.

“There could be between five and ten centimetres of snow north of the Limfjord,” the meteorologist said, referring to the waterway that cuts across the northern part of Jutland, including main regional city Aalborg.

“In the southern part of the country, an equivalent five to ten centimetres of rain could fall,” he added.

Friday’s temperature will be between freezing point and five degrees Celsius, with the north of the country falling in to the lower end of that range and the south the warmer end.

Mist and fog is forecast this evening, caused by various weather fronts moving over Denmark.

That could still be felt on Saturday morning, though it is likely to be a little warmer at 2-6 degrees Celsius. Mild winds could make that fell chiller, but snow is unlikely.

Sunday will see the temperature drop again, to 0-4 degrees Celsisu. Snow is possible, particularly on eastern coasts.

Strong winds in the east of the country and along the coasts will result in a “rather cold 24 hours,” Nielsen said.

Nighttime temperatures are expected to drop below zero throughout the weekend. Motorists are therefore warned to be alert to icy road surfaces.
