The 39-degree heat in Fortaleza meant Holland and Mexico were given the World Cup's first official 'cooling break', as fans were seen retreating to the back of the stands to avoid the scorching sun.
Referee Pedro Proenca allowed three minutes on the half-hour and 75-minute mark to cool off and take in drinks at Estadio Castelao, while supporters maneuvered their way into pockets of shade.
It is worrying, though, with the temperature of Qatar - the controversial hosts of the 2022 tournament - more than capable of reaching in excess of 40 degrees.
