France drought 2026 sets record dry soils, river Doubs runs dry

France is experiencing an unprecedented drought in summer 2026. Soil moisture has fallen to a historic low, surpassing the 1976 record, and groundwater levels are declining across the country. A prolonged heat wave and a dominant Azores anticyclone have limited rainfall, leaving July and August exceptionally dry.

Near the French‑Swiss border, the Doubs river has largely disappeared, exposing bare rock and leaving only isolated pools. Municipalities along the river are resorting to water‑truck deliveries and costly emergency measures to maintain supply for households and businesses. The situation has raised water tariffs and forced local authorities to purchase water from neighboring communes.

Agricultural production is also under pressure. Precipitation in the region is about 55 % below normal, reducing crop yields and milk output. Forests are suffering from bark‑beetle infestations that thrive in the dry conditions, threatening timber revenues. The combined impact on water utilities, farmers, and local economies highlights the severity of the drought.
