With considerable evidence demonstrating the intrinsic importance of weather and climate for tourist decision-making, the projected redistribution of climatic resources as a result of climate change is anticipated to have important consequences for temporal and spatial patterns of tourism demand. Some of the world's leading coastal tourism destinations (Mediterranean and Caribbean) have been identified as becoming ‘too hot’ for tourism. However, the microclimates of coastal tourism areas have not been considered by such assessments. With a focus on thermo-physiologically relevant climatic parameters, this paper examines the adaptive range of microclimatic conditions available in two coastal resort settings in the Caribbean islands of Barbados and Tobago. Recorded weather parameters include air temperature, black globe temperature, relative humidity, and wind speed. The microclimatic results, which are presented using the Universal Thermal Climate Index (UTCI), show that hourly thermal conditions can range up to 4 °C in different outdoor areas of the resort property (beach, garden, pool, cabana). This is salient in terms of characterizing tourism destinations for climate change assessments, as the results reveal that thermal conditions can vary at the micro-scale of a coastal resort, with the ability for tourists to attain thermally comfortable conditions within a single resort property. When a location becomes thermally uncomfortable (i.e. too hot), tourists can change their location (e.g. move from the pool to the beach), providing an onsite adaptive range between 1 °C and 4 °C. The results also demonstrate that thermo-physiologically relevant climatic parameters provide a more precise estimate of the available range of thermal comfort than is inferred from ambient temperature alone. The findings are discussed in the context of tourists’ climatic preferences and reveal that the microclimatic conditions recorded in this study (UTCI 29–36 °C) are well within tourists’ preferred thermal conditions and do not exceed tourists’ thermal thresholds for coastal tourism.
