No, there wasn’t a “phew, what a scorcher!” The closest was the Sun’s silly headline “Scotchio!” It was based on the fact that Andy Murray, a Scot of course, won his Wimbledon match “in 30C heat”.
Elsewhere, national newspaper headline writers avoided puns over articles about the heatwave, although some others also linked it to Britain’s annual open tennis tournament:
“Wilting Wimbledon cuts number of spectators as temperatures hit 41C on centre court” (The Independent); “Game sweat and match to Murray” (Daily Star) and “No sweat for Murray or Federer in the first round – but quite a bit more for spectators” (The Guardian).
