# UK‑Europe heatwave strains agriculture > Live situation record from CLSTR: https://clstr.news/situations/ukeurope-heatwave-strains-agriculture > Updated: 2026-08-03T07:47:55.000Z. Sources: 26. Developments: 4. The heatwave that began in late July 2026 has deepened drought across the UK and parts of the EU. Rainfall fell to roughly 3 % of the July average in southeast England and about 8 % across England and Wales, prompting hose‑pipe bans for more than 20 million people and amber health alerts. Wildfires and grass fires have burned across the countryside. Crop yields have deteriorated further: wheat and oats remain “very, very poor”, broccoli harvests are about half of normal, and the English pea crop is down one‑third. Wholesale vegetable prices have surged, with tomatoes up over 60 %, iceberg lettuce up 90 % and potatoes up more than 40 %. The NFU reports that 9 million tonnes of crops were already lost and that farmers are increasingly relying on imports from Spain and the Netherlands to meet demand. New developments show the crisis accelerating. Record‑breaking temperatures forced Waitrose to carry out its earliest wheat and oilseed‑rape harvest ever at its Leckford Estate in Hampshire, a move the retailer called a “wake‑up call” for climate‑driven farming. The southeast experienced its longest dry spell in over three decades, and fire crews have been battling several grass fires in London. By early August, England recorded only about 10 % of its long‑term July rainfall and Wales about 9 %, making July the driest month on record for southern England and the sunniest for the whole UK. Wheat crops are now roughly half their usual height and oat yields are very poor. The NFU warned that food shortages could follow, urging tax breaks and investment in on‑farm water storage. Hose‑pipe bans now affect around 23 million people, and heat‑health alerts remain in force across multiple regions. ## Claims - NFU President Tom Bradshaw warned that drought could cause food shortages in the UK.
