Abstract
The globally celebrated Olympic Winter Games (OWG) are highly dependent on suitable snow and ice conditions to support elite-level competitions. To determine the range of weather impacts on the Games, this study examines the official Olympic post-Games reports from 1924 to 2010. Impacts include preparations for the Games, holding outdoor opening–closing ceremonies, outdoor sporting competitions, spectator comfort, transportation, and television broadcasts. The study also examines the range of historical adaptations that have developed to manage weather risks at the OWG. Three adaptation eras are identified, spanning the history of the games: emergent adaptation, technological transition, and advanced adaptation. Analysis reveals that while weather-induced impacts have always been a part of the Games, these impacts would be far greater if not for technical climatic adaptations. With the average daytime temperature of host locations steadily increasing from 0.4°C at the Games held in the 1920–1950s to 7.8°C at the Games held in the twenty-first century, it would be difficult to imagine recent host cities/regions successfully delivering the diverse Games programme exclusively on natural ice and snow. The connection between the evolving needs for weather risk management strategies by Olympic organisers and the growth of the Olympics in size and scope is also discussed.
