Same here. 7am temperature 17C. Forecast 21C but reckon it’ll be 25C at least in back garden. Forecast at present is clear and sunny for the available future with temperatures getting towards 30C.
In fact, just saw a piece of BBC which quotes the Met Office as saying that 40C or more is 20 times more likely than in the 1960s and that present-day heatwaves might last a month or more.
