Britain faces worst harvest on record as 'brutal' drought continues
An exceptionally hot and dry summer has caused a 2.5 million tonne shortfall in UK cereal and oilseed production, costing farmers up to £390 million.
British farmers are warning that the extreme summer of 2026 has been 'completely brutal,' with the nation on track for its worst harvest on record. A succession of heatwaves, with a sixth one currently brewing, has compounded the impact of an exceptionally hot and dry spring. According to experts, these climate conditions could reduce the country's cereal and oilseed harvest by 2.5 million tonnes compared to earlier forecasts.
The economic impact of this shortfall is significant, with analysis from the Energy and Climate Intelligence Unit (ECIU) suggesting that UK farmers could face losses as high as £390 million. These figures come as a sharp contrast to forecasts made in March and April, when European and US agricultural bodies suggested that yields were set to be at or above ten-year averages.
However, fresh harvest data from the Agriculture and Horticulture Development Board (AHDB) paints a much bleaker picture. Wheat, barley, and oat yields are all expected to be down. Wheat, with approximately half of the crop already harvested, is averaging 6.8 tonnes per hectare, a figure well below historical averages.
If the provisional yield estimates hold, the total UK cereal and oilseed harvest will reach 19.5 million tonnes. This would make 2026 the worst year for agricultural output since detailed records began in 1984, overtaking the previous low of 2020. While oilseed rape has shown some resilience with better yields, it is not enough to offset the broader decline across other key crops.
The ECIU warns that 2026 is likely to be one of the five worst harvests on record, noting with concern that four of these five poor seasons have occurred within this decade alone. The increasing frequency of such extreme weather events is highlighting the vulnerability of UK agriculture to the ongoing impacts of climate change.
