Skiers have been left dismayed after arriving at resorts with little to no snow.

Warm temperatures in the last two months of 2015 have raised concerns for those looking forward to ski and snowboard holidays.

In the resort of Leysin, Switzerland, the snow has melted as a result of mild temperatures throughout the last few days.

Skiiers can still be seen attempting to tackle the slopes, which are maintained by artificial snow machines.

Climatologists say the warmer winter is a result of El Niño, which has warmed the Pacific Ocean.
