Milk, wine, salad: how your food will be affected by the summer of heat

The United Kingdom is experiencing its fifth consecutive climate-driven heatwave, with nearly three-quarters of England in drought conditions, creating widespread effects across the agricultural sector.

Livestock farming faces significant challenges as persistent dry conditions have reduced grass growth to approximately half of normal levels for this time of year. Farmers typically use summer months to harvest forage for winter feed storage, but this critical season has been severely curtailed. Some operations have already begun drawing down winter reserves earlier than planned, while others anticipate needing to purchase supplemental feed. Milk production has declined by roughly 1% as dairy cows struggle with reduced feed availability and heat stress. A shortage of sheep shearers has further complicated efforts to maintain animal comfort. Industry analysts suggest long-term adaptations such as planting shelter trees and installing climate control systems in agricultural facilities, though many farmers express concern that current conditions may represent the beginning of a recurring pattern.

Cereal and grain production faces the worst outlook, with forecasts indicating the smallest harvest in approximately four decades. Wheat yields are expected to drop from the typical 7.9 tonnes per hectare to around 6.7 tonnes, representing a loss of approximately £390 million in revenue. A combination of excessive spring moisture followed by dry conditions during critical growth stages, record May temperatures, and ongoing July droughts have severely stunted grain development. Southern England recorded its driest July on record, with minimal precipitation across much of the country since mid-June.

In contrast, fruit and wine sectors are experiencing favorable conditions. Soft fruits including strawberries, raspberries, and stone fruits have thrived, producing smaller but more intensely flavored crops. Cider producers are anticipating potentially exceptional yields. Wine producers in the UK report healthy vineyard conditions and promising ripening progress.

European agricultural regions are also experiencing significant difficulties, with heatwaves and fires contributing to an estimated €2 billion in lost revenue across the continent. Agricultural leaders warn that the cumulative impact of weather volatility—following record winter wetness and extreme summer heat in preceding years—risks creating a damaging cycle that could undermine farming operations’ capacity for future production cycles.
