The Swiss air rescue service, Rega, reports it was called out 82 times between Friday and Sunday after winter sports accidents.
Rega spokesman Gery Baumann said 40 missions were flown on Friday, 22 on Saturday and 20 on Sunday.
Since November 1, the non-profit foundation has flown on 311 missions, two to three times more than in previous years.
Rega said one of the reasons for the increase was the early start to the season after snow had fallen. But it also cited the good weather and the timing of this year's holiday period.
Many skiing accidents include knee, shoulder and back injuries or broken bones, but others involve serious head or internal injuries.
Baumann said the most severe injuries happened as a rule after collisions.
