Global warming
Last Monday, Tunisia crossed a critical heat threshold. According to official surveys of the National Institute of Meteorology (INM), the city of Kairouan recorded an exceptional temperature of 48 ° C, thus establishing a record for this summer.
This heat wave, which is part of a context of global global warming, has affected almost all of the country’s regions, with abnormally high temperatures compared to seasonal averages.
This heat wave is due to a powerful current of hot air coming from the Sahara, commonly called “Chergui”, which blows on the interior of the country and accentuates the temperatures felt. According to the INM, the temperatures observed are 7 to 11 degrees higher than seasonal normal.
This extreme phenomenon is not isolated. In recent years, Tunisia has recorded an upsurge in scorching days exceeding 45 ° C, especially in the interior areas. Summer 2024 had already recorded historical records in the south of the country. In 2023, Kébili had reached 50.2 ° C, a national record.
