France was battered by brutal cold during the second half of April and first half of May — the key planting window — with the mercury hitting all-time lows.
France is the third largest corn exporter in the world, meaning a delayed or poor harvest will have a pronounced impact on global markets.
Severe frosts have been widespread from the lowlands to Brittany to South Ouest, with farmers regularly lighting frost-fires in an attempt to protect fragile crops.
On May 6, the nation averaged its coldest May morning since 1979, at 2.5C (36.5F).
A fresh bout of frigid air is forecast to plunge into central Europe next week, likely persisting through the remainder of May.
