In late May 2026, Western and Central Europe are enduring an unprecedented early heatwave, driven by a powerful “heat dome” that traps warm air from Northern Africa. Temperatures have soared 10–16°C above seasonal averages, shattering dozens of monthly records.

In the UK, London’s Heathrow Airport hit 33.5°C on May 25, the highest May temperature in nearly 80 years. France faces its earliest severe heatwave on record, with southwestern areas reaching 37.1°C and 8 departments issuing orange alerts. Spain and Portugal are the hottest, with southern Spain at 38°C and parts of Portugal approaching 40°C. Belgium, Germany and the Netherlands also see highs of 32–35°C, far exceeding typical May norms.

Amid such extreme heat, insulated cooler bags (thermal bags) have become essential. Made of multi-layer foam and reflective liners, they slow heat transfer, keeping cold foods chilled and hot items warm for hours. In 35°C heat, a quality insulated bag maintains safe temperatures for perishables like dairy, meat and salads, preventing bacterial growth and spoilage. It also keeps drinks cold and snacks fresh for picnics, commutes or grocery runs. Lightweight and reusable, these bags reduce food waste and ensure food safety—simple but vital tools for coping with Europe’s new normal of extreme heat.
