Tunisia lives, at the start of the week, a final summer start marked by a strong heat wave. This occurs before the expected arrival of abundant rains. According to the forecaster of the National Institute of Meteorology, Sobhi Ben Ahmed this Monday, September 8, 2025, temperatures will remain high today and tomorrow. They will exceed the seasonal averages in places.
In the Grand Tunis, the thermometer should oscillate between 37 and 38 degrees, accompanied by winds from Sirocco (Chihili). On the ribs and in the mountainous areas, the maximums will vary between 31 and 35 degrees. While the interior of the country will experience temperatures between 36 and 41 degrees. The sea, on the other hand, will generally remain calm roughly agitated.
On the sky side, the morning will be partially cloudy. In the afternoon, we will see the appearance of local thunderstorms. The latter will be accompanied by scattered rains. They will first appear in the regions of the west of the north and the center, before winning certain areas of the East. Finally, localized hail falls are not excluded.
But it is from Wednesday, September 10, that the weather situation should tip over. A strong breakdown system will settle on Tunisia, resulting in a real degradation of time.
The northwest regions as well as the Grand Tunis will be the first concerned with intense precipitation. They are known as Ghassalet Ennawader (detergent of barbarism figs), announcing the transition to the fall. Temperatures will then fall sensitively, ending this late scorching sequence.
