He said: “Climate change has raised the average temperature in the UK’s summers and also increases the likelihood of more extreme temperatures during hot seasons and heat waves. “Reaching 34C in June is a rare, but not unprecedented, event in the historical climate records for the United Kingdom. “But if it happened this week, it would be remarkable that it would have happened in three days during the last six June.” He added that the other days were June 21, 2017 and June 29, 2019. Prior to that, the only previous June where England had seen a number of stations reach 34 C or higher were 3 June 1947, 29 June 1957 and 26-28 June 1976. Met Office forecaster Greg Ducherst added that the last part of this week is expected to be “very hot”. He said: “The vast majority of England and Wales will see a wonderful day on Wednesday, albeit slightly different in Northern Ireland and Scotland, where it will be cloudy and rainy. “It will be very hot especially in the southeast, with the temperature reaching 28 degrees Celsius, which would make it the hottest day of the year so far. “This will be overcome on Thursday, with the mercury rising again to 29 degrees Celsius before it reaches 33 degrees Celsius and even 34 degrees on Friday.
