French Potato Yields Set for 30-Year Low as Heatwave and Drought Cut Harvest by 23%
Key takeaways
- 37.4 t/ha expected French yield, lowest in over 30 years
- 23% smaller harvest than last year, losses above 2 Mt
- 173,400 ha planted after a 9.7% cut in area this season
- 400 million euros of damage estimated by growers' union
Why it matters
- For farmers
- Growers with uncontracted potatoes in north-west Europe are positioned to benefit from prices of €230–310 per tonne.
- For processors
- Expect tighter raw-material supply and higher free-buy prices in north-west Europe this season; secure volumes and review contract coverage early.
- For traders
- The French shortfall supports firm prices across Germany and the Benelux; factor a genuine EU supply deficit into forward positions.
60-second summary
France, the EU's largest producer of processing potatoes, is heading for its lowest yields in more than 30 years, according to growers' association UNPT. UNPT forecasts about 37.4 t/ha for 2026, against 43.5 t/ha in 2025, and a harvest 23% smaller, which means more than 2 million tonnes lost. Two factors combined: growers had already cut planted area by 9.7% to 173,400 ha after the oversupplied 2025 season, and July was record-hot and dry, with rainfall 67% below normal. UNPT puts the total damage at no less than 400 million euros. The shortfall helps explain why processing potato quotes in Germany and the Benelux have climbed to 230 to 310 euros per tonne. In effect, the price cycle that began with the 2025 glut has turned into a real supply deficit in north-west Europe. The yield and loss figures are UNPT forecasts rather than final harvest data, so they may change as lifting is completed, but processors and traders should plan for tight raw-material supply this season.
UNPT, the French national potato growers’ association, forecasts yields of around 37.4 t/ha for the 2026 crop, down sharply from 43.5 t/ha in 2025 and the lowest level in more than 30 years. The harvest is expected to come in 23% below last year’s, with losses exceeding 2 million tonnes. Planted area had already been reduced by 9.7% to 173,400 hectares following the oversupplied 2025 season, and the decisive blow came from a record-hot, dry July, with rainfall 67% below normal. UNPT estimates the total damage at no less than €400 million.
The implications extend well beyond France. As the EU’s largest producer of processing potatoes, France’s collapse in output helps explain the price surge already observed in Germany and the Benelux countries, where quotes have reached €230–310 per tonne. The French figures put concrete numbers behind the scale of the EU supply deficit, confirming that the price cycle set in motion by the 2025 oversupply is now translating into a genuine shortfall across the bloc’s most important growing region.
