UK provisional peak of 37.7C shatters previous record by huge margin, while Germany hits all-time high of 41.7C Last week’s heatwave across western Europe shattered national June records and set new all-time highs. The UK recorded a provisional high of 37.7C at Lingwood in Norfolk on Friday 27 June, smashing the previous June record of 35.6C, set in 1976. Such a margin is exceptionally rare: temperature records are typically broken by 0.1C or 0.2C, not a remarkable 2.1C.
