Last month was the hottest June on record in Britain, the country's national weather service said on Monday, warning that human-induced climate change was making such temperature records increasingly likely.
Record heatwaves have become a worldwide pattern, as scientists warn that efforts to halt a rise in temperatures are falling short of what is needed to avert the most catastrophic effects of global warming.
Britain's Met Office said the average mean temperature of 15.8C in June was the highest in a series going back almost 140 years, beating a previous record of 14.9°C set in 1940 and 1976.
Last year, Britain recorded its hottest ever day when temperatures surged past the 40 Celsius (104 Fahrenheit) mark for the first time, causing disruption to infrastructure like airports and railways, and sparking wildfires.
Describing the latest record as bearing a "fingerprint of climate change" the Met Office said a study by its scientists had found the chance of June being hotter than 14.9C had at least doubled since around 1940.
"Alongside natural variability, the background warming of the Earth’s atmosphere due to human induced climate change has driven up the possibility of reaching record high temperatures," said Paul Davies, Met Office Climate Extremes Principal Fellow and Chief Meteorologist.
Earlier in the month, British water supplier South East Water introduced a temporary ban on hosepipes and sprinklers in the English regions of Kent and Sussex following high temperatures and rising demand for drinking water.
The Met Office also said a marine heatwave affecting the North Atlantic had played an underlying role in raising land temperatures in Britain and said rainfall during June had been 68% of its average level.
