Intense Heatwave from France Set to Raise Temperatures Above 30°C in Southern and Central Sweden

Southern and central Sweden is bracing for a significant heatwave originating from France, with temperatures forecasted to rise to around 30 degrees Celsius or higher by late June 2026. The Swedish Meteorological and Hydrological Institute (SMHI) has issued heat warnings for parts of Kalmar län, most of Götaland, and Värmland. According to meteorologist Catarina Wahlström, some areas may reach as high as 33 degrees Celsius, particularly on Saturday. The heatwave is expected to peak over the weekend and persist into early next week before temperatures likely return to normal by midweek.

The hot spell follows extreme heat conditions in southern and western Europe, where temperatures near 45 degrees Celsius have been recorded and over half of France's regions are under red heat warnings. Meteorologist Max Schildt from SMHI explained that a low-pressure system over the Norwegian Sea is drawing the heat northward into Sweden. Tropical nights—when temperatures stay above 20 degrees Celsius—are predicted especially in southern Sweden, with nighttime temperatures potentially reaching 25 degrees in southern Götaland.

The warm and dry conditions, accompanied by some wind, raise concerns about an increased risk of forest fires. SMHI advises vulnerable groups such as the elderly, pregnant women, young children, and individuals with underlying health conditions to be cautious, stay hydrated, and avoid heat exposure during these peak days. Rain showers might accompany the heat, particularly in northern Sweden, but southern regions will mostly experience the dry heat.

While this heatwave is notable, SMHI climate expert Gustav Strandberg notes it remains unlikely that Sweden will reach extreme temperatures like 40 degrees Celsius within this century, as such a heat would require a substantial climatic shift. Currently, Sweden's highest recorded temperature stands at 38 degrees Celsius. Nonetheless, the health risks associated with sustained high temperatures make this heatwave a significant event for public awareness and preparedness.
