• Previous research has found higher levels of heatwave mortality and morbidity among urban residents with a migration background because of their social, health and environmental conditions. The purpose of the study was to investigate and compare heat induced changes in the outdoor recreation behaviours of Turkish migrants with those of non-migrants on hot days in Vienna. Specifically, the study compared coping behaviours due to heat such as inter-area, intra-area, temporal and activity displacement between migrants and non-migrants. The study interviewed 400 migrants and non-migrants in four public green spaces of different area sizes and asked about their outdoor recreation motives and activities, as well as behavioural changes, due to summer heat. Results show that migrants have different motives for visiting urban green spaces on hot days, and that they visit these less frequently on hot days compared to non-migrants. While both groups shift their outdoor uses more to shady areas and the cooler times of the day, more migrants visit green spaces in the afternoon, perform more energetic recreational activities, and use sunnier sites more frequently than non-migrants on hot days. Few migrants and non-migrants stated that they would visit alternative green spaces when it is hot. The results indicate that migrants’ behaviours result in higher heat exposure, while making less use of the opportunities larger green spaces such as forests can provide for heat relief. Recommendations on how green and city planners could reduce heat related health risks for both study groups are presented.
