The UK is on track to record its hottest summer ever, continuing a trend where record-breaking temperatures are occurring with increasing frequency.
Key facts
- •All five of the UK's hottest summers on record have occurred since 2000.
- •The 2025 summer record was broken by a margin of 0.34C.
- •Europe is warming at roughly twice the global rate.
- •The UK's summer temperature records are being overtaken with increasing speed.
The UK is expected to declare summer 2026 as the hottest on record, marking a significant jump in temperature. This follows a trend where all five of the UK's hottest summers have occurred since 2000. In 2025, the previous record was surpassed by a margin of 0.34C, and current data suggests that record has now been broken again.
Rapidly warming climate trends
Climate scientists use the term "record-shattering" to describe records broken by unusually large margins, a phenomenon linked to rapid climate warming. While weather patterns will continue to produce cooler summers, the frequency of extreme heat records is increasing. The UK is situated on the western edge of Europe, which is warming at approximately twice the global rate.
Factors influencing UK temperatures
Several factors contribute to the warming trend in Europe, including the fact that land heats faster than oceans and parts of the continent extend into the rapidly warming Arctic. Additionally, shifts in weather patterns have led to more frequent and intense summer heatwaves. Scientists are currently researching the specific contribution of each factor to the overall warming of the UK's climate.
