Met Office confirms highest temperature ever recorded in... Monday September 16, 2019 On the 25th July, a temperature of 38.7°C was recorded in Cambridge Botanic Garden, confirmed by the Met Office as the highest that has ever been recorded in the UK.The recent European heatwave also set national record across various other countries across the continent. This included: Germany (42.6°C), Belgium (41.8°C), Luxembourg (40.8°C) and the Netherlands (40.7°C). The rapidly increasing temperatures were a result of hot air being drawn northwards from Africa in a wide swathe over Europe. Such an occurrence is not uncommon, but with parts of North Africa being on average 2°C hotter than pre-industrial times the swathe of air was hotter than it would have been without the effects of global warming.
