Second homes are essential resources for tourism and recreation. Climate change is projected to transform tourism geographies and threaten economic and recreational activities. Based on building and housing register data and national models for climate change hazards, this paper investigates whether second homes in Denmark are potentially affected. Five different hazards are used to describe climate risk based on the RCP8.5 scenario: sea level rise, storm surge events, coastal erosion, flooding from watercourses, and terrestrial groundwater. It is estimated that between 2020 and 2070 a significant number of second homes will potentially be affected by one or more of these hazards, with terrestrial groundwater being the most frequent. GIS-analysis shows the detailed geographical distribution of the affected second homes, while regional grouping highlights the most affected regions. A compound risk analysis demonstrates that a significant proportion (approximately 25%) of the Danish second homes will be affected by either one or more hazards. The analysis thereby highlights how amenity rich geographies are threatened by climate change, which could cause these areas to become risk prone. This provides a background for discussing the implications for land use policy of transforming geographies. The article highlights a need for strategic planning and active engagement with second to protect the recreational potential of second homes and local economies in coastal zones.
