The weather forecast makes scary reading for the rugby stars contesting the Brisbane 10s this weekend.
Organisers Duco will turn to World Rugby's heat welfare guide in what will be sweltering conditions for the inaugural tournament.
The Brisbane weather forecast is predicting maximum temperatures of 36 and 38 degrees celsius, with extreme sun protection warnings for both days. Plenty of water and rolling subs will be the order of the day.
It will be especially tough for Japan's Panasonic Knights, whose home city is experiencing temperatures around one degree, and the Chiefs have travelled from Hamilton, where the temperatures are about 15 degrees.
Chiefs stalwart Liam Messam told the Sydney Morning Herald: "It's something that has to be managed, because it can be quite dangerous if it gets too hot, as we saw with the A-League last week."
