A report from the Bureau of Geological and Mining Research, published on June 13, 2025, indicates that while the overall condition of France's groundwater is deemed 'satisfactory', there are significant concerns in specific areas, particularly in the North, Aude, and Pyrénées-Orientales.

Groundwater levels across France are showing a mixed picture, with northern regions and the southwestern Paris Basin maintaining stable levels, while southern areas, especially Roussillon and Corbières, are experiencing critically low water levels despite some recent rainfall.

Hydrologist Violaine Bault highlighted that although groundwater levels are higher than last year, they remain significantly below normal due to insufficient winter rainfall that failed to recover from previous deficits.

Overall, groundwater levels are depleting across France, a trend expected to persist until autumn, with varying conditions across different regions.

Currently, many northern aquifers are in a draining phase, exacerbated by higher temperatures and vegetation growth that hinder rainfall infiltration, leading to a 75% decrease in water levels during May.

Concerns are mounting that prolonged drought conditions could severely impact aquifers, with potential implications for irrigation, pool filling, and tourism, possibly resulting in water use restrictions.

Forecasts for the coming months are particularly pessimistic regarding rainfall and temperatures in regions vital for viticulture and tourism, such as Roussillon.

In contrast, forecasts for aquifers in southern France and Corsica appear more optimistic due to relatively moist soils observed in May, although additional rainfall in June would be beneficial.

As of June 1, 2025, 35% of groundwater observation points are below monthly norms, while 19% are comparable to historical averages, and 46% exceed normal levels, indicating a decline from May 2024 when 70% were above norms.

Groundwater levels vary significantly across regions, with reactive aquifers in the North showing lower levels, while inertial aquifers in the South and Corsica remain above normal.

The commune of Millas in the Pyrénées-Orientales was notably affected by drought conditions in May 2023, highlighting the ongoing challenges faced by this region.

Météo-France has indicated that higher than normal temperatures are likely for the summer of 2025, particularly in Corsica, although rainfall forecasts remain uncertain.
