Southern Norway braces for extreme heat

Southern and eastern Norway are set for several days of temperatures above 25°C, with some areas possibly reaching 28–29°C, according to the Norwegian Meteorological Institute.

Meteorologist Aslaug Skålevik Valved told Dagbladet that the highest temperature recorded in Norway so far this year was 27.6°C in Alta on 5 June, but this could soon be surpassed. The heatwave, originating from southern Europe, is expected to bring multiple summer days above 25°C to southern and eastern Norway starting today.

While a formal heatwave in Norway requires five consecutive days with temperatures of at least 27°C, Valved noted that this threshold may be met this week. However, she clarified that Norway is not expected to reach the extreme temperatures seen further south in Europe, where some areas are experiencing 40°C.

The meteorologist also warned of potential heavy rain showers and thunderstorms as unstable air moves in from the UK late Friday, affecting southwestern and southeastern Norway. The warm air increases moisture capacity, raising the risk of intense downpours.

In neighbouring Denmark, the Danish Meteorological Institute (DMI) has issued a heatwave warning, with local temperatures possibly hitting 35°C over the weekend.

Valved emphasised the need for precautions, urging people to stay hydrated, seek shade, and protect vulnerable groups such as children, the elderly, and pets. She also highlighted increased wildfire risks due to the high temperatures.

The Red Cross echoed these warnings, advising the public to drink sufficient water, eat properly, and avoid waiting until feeling unwell to take breaks from the sun.
