The summer of 2026 in the UK is definitely making waves! In May, temperatures climbed up to 35.1°C at Kew Gardens, thus breaking all May records that date back to 1922. In June, even more heat was recorded at 37.7°C in Norfolk and the record-breaking temperatures were registered at over 150 weather stations at the same time. Now July is delivering the third heatwave in succession in southern and eastern parts of the country without giving any sign of coming relief.
