France is facing an "alarming" rainfall deficit in September, with regions from Corsica to the Southwest and through Lorraine experiencing significantly below-average precipitation. According to Météo-France, all of its automatic weather stations recorded fewer rainy days than usual this month. Rainfall forecasts for the upcoming days are not expected to alleviate the drought, which has become both exceptional and prolonged. Simon Mittelberger, a climatologist at Météo-France, notes that typically, September brings relief from the summer heat, but this year, the rains have been absent. He explains that the drought indicators for several regions have reached record levels for September, with some areas experiencing drought conditions not seen even during the typically dry summer months.
The drought has affected a wide range of regions, including the Hautes-Pyrénées, the Pyrénées-Atlantiques, the Landes, the Lot-et-Garonne, parts of Nouvelle-Aquitaine, the former Languedoc-Roussillon region, the Rhône valley, and Corsica. Rainfall totals have been "extremely low" in many places. For instance, the Moselle region received only one to five millimeters of rain in September, far below the typical 60-70 millimeters. Similarly, areas along the English Channel, known for their high rainfall, saw only 10 to 20 millimeters of rain compared to the normal 70 to 80 millimeters. The number of rainy days has also dropped sharply, with some communes, such as Chastreix in the Puy-de-Dôme and Scheibenhard in the Bas-Rhin, experiencing a deficit of 10 rainy days compared to the norm.
The situation is causing significant concern across the country. Although some rain is expected on Wednesday, September 30, and Thursday, October 1, it may not be enough to reverse the drought. Much of the rain that fell between mid-August and the end of September has already evaporated, leading to water restrictions in many communes. In some areas, water is being transported by tank trucks, as seen in the Isère region. Additionally, dry conditions have placed several departments at a "high risk" of forest fires, and river flows are at very low levels. The prefecture has declared a "crisis" situation for the Garonne river between the Pyrenees and Toulouse. Agricultural areas, which require substantial water, are continuing to suffer, and farmers in Corsica have even protested to request aid.
The current drought is not an isolated event but part of a broader trend linked to global warming. Simon Mittelberger explains that rising temperatures and changes in precipitation patterns are expected outcomes of climate change. The extension of summer conditions into autumn is a signal that scientists have long predicted. Since the 19th century, the Earth's average temperature has increased by 1.3°C, and this rise is definitively linked to human activities such as the burning of fossil fuels. Scientists warn that this rapid warming threatens both human societies and biodiversity. However, solutions such as transitioning to renewable energy, practicing energy sobriety, and reducing meat consumption are available to address these challenges.
