Norway’s eastern regions are bracing for a multi-day heatwave starting Thursday, with temperatures expected to reach 30 degrees Celsius or higher as a new weather system moves across Europe. Meteorologists predict that areas including Oslo and Drammen will face extended periods of warmth, while northern and mountainous regions of the country continue to experience significantly cooler conditions and even snow.
Heatwave criteria and regional warnings
The Nordic definition of a heatwave requires five or more consecutive days with temperatures reaching at least 27 degrees Celsius. According to meteorologist Leonidas Tsopouridis, the Østlandet region is expected to meet these criteria from Thursday through the following week. Drammen may see temperatures climb as high as 32 degrees, while Oslo faces a steady climb in heat leading into the weekend, including a potential “tropical night” on Saturday with temperatures between 20 and 22 degrees.
The contrast across Norway remains sharp. While the east warms up, Trondheim will remain cool, with temperatures hovering around 12 to 13 degrees before rising closer to 20 degrees on Saturday afternoon. Mountainous areas like Vikafjellet and Strynefjellet have recently reported snow, and regions in Sør-Trøndelag and Møre og Romsdal have faced snow hazards at elevations above 1,000 meters. Meanwhile, northern parts of the country, including Tromsø and Finnmark, can expect rain and temperatures around 15 degrees.
The record for the highest temperature ever recorded in Europe was set in Italy in 2021, when the mercury reached 48.8 degrees Celsius.
Extreme heat across Southern Europe
The warming trend in Norway coincides with a broader, more severe heatwave affecting Southern Europe. According to the World Health Organization (WHO), parts of the continent may face several deadly weeks as a new, powerful heatwave moves in from the Atlantic. Temperatures in Portugal and southern Spain could reach 43 degrees in the coming days, while Sevilla is expected to bear the brunt of the heat.
Meteorologists note that while Alicante may see slightly lower temperatures around 36 degrees, high humidity levels could make the heat feel as intense as in other areas. During a heatwave in June, France, Belgium, and the Netherlands recorded 3,700 more deaths than normal. The WHO reports that fewer than half of European member states currently have emergency heat-preparedness plans in place, though those that do have historically managed such weather events more effectively.
The disparity in temperatures between the southern regions of Europe and the varying conditions across Norway highlights the volatile nature of current weather patterns. The primary risk during these events, as noted by health authorities, is the cumulative physiological stress on the body, particularly when high temperatures persist over several consecutive days.
Staying safe during the VM quarterfinals
With Norway playing in the quarterfinal of the football World Cup this Saturday, many fans are expected to gather in public spaces.
Ranhoff advises fans to prioritize non-alcoholic beverages and to avoid relying on alcohol during the festivities. “The lower the alcohol percentage, the better,” she states, noting that the body loses salt through sweat, which can be replenished by consuming food like potato chips. Signs of heat-related illness include dizziness, headache, nausea, and lethargy. Ranhoff recommends staying in the shade, using fans, and cooling the body with water or wet clothing if individuals feel they are overheating.
Frequently Asked Questions
What defines a heatwave in the Nordic region?
A heatwave is defined as five or more consecutive days where temperatures reach 27 degrees Celsius or higher.
How can I tell if I am dehydrated in the heat?
According to Anette Hylen Ranhoff, the color of your urine is a key indicator. It should be light yellow; urine that is dark yellow or brown may indicate that you have not consumed enough fluids.
Are all parts of Norway experiencing the same weather?
No. While the Østlandet region is entering a heatwave, other areas are significantly cooler. Trondheim, for example, will see temperatures around 12 to 13 degrees, and snow has been reported in mountainous areas like Vikafjellet and Strynefjellet.
How are you planning to manage the heat during the upcoming weekend?
