Sochi Winter Olympic Games the warmest ever

The Winter Olympic Games in Sochi, Russia are expected to be the warmest ever, with temperatures reaching 20 degrees in the coming days.

The temperatures will make the Olympic venue warmer than the South of France, Hong Kong or New Delhi, and it will be hotter than some days of the London Olympics in 2012.

Several competitors have complained about the weather, with some snowboarders describing the half-pipe course as "dangerous", "crappy" and "mush".

Other sports, such as the biathlon, have been affected by the soft snow.
