Summer 2026 Heatwave Threatens UK Produce
14 Sep
Summary
- Record-breaking summer temperatures in the UK linked to climate change.
- Extreme heat has caused crop failures for vegetables like broccoli and peppers.
- Consumers may face 'shrinkflation' and higher grocery bills due to shortages.

The summer of 2026 was the UK's hottest on record, with extreme heat and drought conditions exacerbated by human-induced climate change. These relentless heatwaves have had far-reaching consequences, affecting wildlife, energy demands, transport, and public health.
Agricultural sectors have been hit hard, with reports indicating significant crop losses. Brassica crops like broccoli and cauliflower have suffered, becoming dormant or smaller, while up to 40% of sweet pepper supplies were lost in some regions. Potato yields also face penalties, potentially dropping by 30-40%.
These yield reductions, coupled with rising energy, fertilizer, and labor costs, are expected to lead to increased food prices. Experts predict consumers may experience "shrinkflation" and higher costs, with potato and onion prices for the following year already anticipated to rise significantly.
